Niacin bottle label. Description in quote below.

Experience: Temp full body sunburn

“flushing”

Niacin is a B-vitamin. Sunburn effects lasts 30-60 mins.

You will feel: warm, cozy, itchy.

you’re not having an allergic reaction it’s supposed to be like that

-Handwritten on 500mg Niacin bottle at Lighthaven

I recommend it.

It didn’t feel like a sunburn to me. You know the feeling of a limb falling asleep? It was like that but only 20% as strong, and a full body experience.

Taking it was unexpectedly mindful. I was afraid it would be unpleasant enough to incapacitate me, but to the contrary, it connected me to my bodily sensations.

As I edit this post, I just took another.

One tip: no matter how itchy you get, resist itching.

Experience Log

19:04 took 500mg capsule of Niacin

19:09 maybe barely starting to feel sore

19:12 feeling a mild warmth in my stomach, right where the esophagus connects, soreness is definitely a symptom and starting to intensify

19:16 a bruise on my shoulder from a few weeks ago is throbbing, very similar sensation to getting a shot

19:18 I’m noticing pain in my lower back that I wasn’t noticing earlier, I’m starting to feel more alert

19:19 I’m going to drink some Rooibos tea

19:20 the pain in my stomach has become a bit sharper, it reminds me a little bit of the feeling of a whole Cheez-It going down my esophagus, but in my whole stomach

19:20 I’m starting to be aware of pain in my upper thigh, just a little bit of tingling

19:21 I’m noticing that my hands are a bit sore while I’m typing

19:21 I’m feeling a tingly itchy sensation first on the back of my neck, and now on the front of my chest

19:22 I also am starting to feel the itchy sensation on the top of my hands

19:22 my foot is throbbing a little bit, kind of like I pulled a muscle

19:22 I’m noticing that my eye muscle is just a bit sandy, and starting to be a bit itchy

19:23 Soreness has extended into my fingertips

19:25 my hands are definitely a bit sore, as though I typed for a long time already

19:26 Rooibos tea again. Drinking doesn’t really feel any different

19:29 I’m feeling quite itchy all over my face, even inside of my nostrils

19:32 I’m starting to notice that my body kind of feels a bit like after constricting blood flow (“fell asleep”), particularly noticing this sensation in my upper left thigh and around my elbows

19:33 Swallowing is starting to be a little bit more noticeable, my throat feeling a bit more bloated

19:33 My left foot is continuing to throb a little bit more

19:34 I’m noticing my tailbone a bit more

19:34 I feel a little bit lighter, and picking up my mug feels a little bit more ethereal

19:35 I’m just starting to notice itchiness on my collarbone, itchiness on my hands feels more intense

19:36 Noticing itchiness inside of my ear for the first time

19:36 My right index finger is pretty itchy

19:37 I finished my Rooibos tea

19:38 My ears tearing up a bit

19:38 I’m pretty itchy under my right arm pit

19:38 My left eye that was previously feeling sandy is now particularly itchy, and starting to water

19:39 My right eye is also watering, it feels like I’ve been using it for a long time

19:39 Inside my left elbow is now particularly itchy

19:40 My muscles are starting to feel a bit sore all over the place

19:41 My right cheek is also feeling pretty tingly now

19:41 I’m noticing tingling around the crown of my head

19:41 My heartbeat is more noticeable

19:42 The top of my head is now on fire with tingling, my hands are feeling very similar

19:42 I can feel my neck muscles when I move them, my neck is starting to tingle quite strongly

19:42 My heartbeat in my neck has fairly high intensity, and the tingling now feels more like fire

19:43 I’m starting to get quite warm, especially on the back of my hands, my ears, and the back of my neck for now

19:46 I feel like my body is humming

19:47 My upper arms are also starting to feel quite warm

19:47 All over itchiness has given way to buzzing/tingling/burning

19:47 My hands are noticeably redder

19:47 I’m feeling some pressure inside of my ear canal like changing altitude

19:48 My calves feel cooler than usual, but it’s possible that it is just because the rest of my body is flushed

19:53 I got up and walked around a bit while trying to convince people to take Niacin, when sitting down I noticed tingles in my upper thigh

19:53 My body is pretty much completely warm now, in a ring around my lungs

19:54 Redness still hasn’t spread too far past my wrists

19:57 I now feel like I need to move around to feel the Niacin

19:57 My eyelids feel a little bit sandy, closing my eyes feels little bit like it does when I have red-eye or my eyes are particularly dry after watching TV for a long time

19:58 Tingling now only really happens when I move around, just a little bit of tingles wherever I move something

19:59 The Niacin is now feeling very normal, maybe just a bit of tingling

20:02 I feel warmth in my stomach in particular again

20:02 Noticing pressure in my ears

20:16 I’m starting to get a bit of chills because my body is changing in temperature

20:19 My skin feels slightly flaky or something when I touch it, I can imagine how itching could quickly intensify the experience and make it much more unpleasant

20:20 My stomach is starting to feel a bit sore, my eyes are watering again

20:22 My eyelids definitely still a bit heavy

20:27 Starting to feel chills all over as the Niacin wears out

20:28 Noticing the tiniest bit of a headache in my right temple

20:32 I still get a little bit light headed and tingly, and a bit stomach achy, starting to feel fairly cool, some amount of cold chills are happening all over my body

20:34 I feel like the symptoms are pretty much all over, just some chills, and a tiny amount of tingles in my belly and tops of my feet + when I move around vigorously

20:44 Symptoms are almost completely gone by now, only a little bit of warmth in my stomach left

20:55 I still feel a little bit light headed as an aftereffect

21:31 My only noticeable symptom at this point is a little bit of a stomach warmth and a little bit of soreness

21:40 I still feel a little light headed especially when I walk around
