In the spirit of https://www.lesswrong.com/posts/fFY2HeC9i2Tx8FEnK/my-resentful-story-of-becoming-a-medical-miracle , some anecdotes about things I have tried, in the hopes that I can be someone else's "one guy on a message board. None of this is medical advice, etc.

• No noticeable effects from vitamin D (both with and without K2), even though I used to live somewhere where the sun barely shines and also I never went outside, so I was almost certainly deficient.
• I tried Selenium (200mg) twice and both times I felt like utter shit the next day.
• Glycine (2g) for some odd reason makes me energetic, which makes it really bad as a sleep aid. 1g taken a few hours before bedtime is substantially less disruptive to sleep, but I haven't noticed substantial improvements.
• Unlike oral phenylephrine, intranasal phenylephrine does things, albeit very temporarily, and is undeniably the most effective thing I've tried, though apparently you're not supposed to use it too often, so I only use it when it gets really bad.
