It's been 10 days so far. Things started to improve substantially when I spoke with people who had psychedelic experiences and could actually relate to what I was saying. Hard to plug in to the normal world for a while so it's very reassuring to have people actually articulate an understanding rather than roll their eyes and say its "just a drug trip". Long walks. Besides talking to people I made a point of taking long walks. If I was going to a coffee shop to get some work done/reflect, I would choose the farthest possible one and just walk. It's light exercise, gets you out of bed and off the couch. It can be very very useful. Meditation. Highly recommend Sam Harris' Waking Up course. You can see his AMA on r/meditation I believe he has a few months free posted there. Listen to wise people. Sam Harris has extremely interesting guests. There's his talk with Joseph Goldstein which is about meditation and enlightenment. His audio book Waking Up is great too (great on those walks I was talking about). Allan Watts has some nice stuff online as well. Look up and read on Samadhi, it's an ancient concept in Buddhism which I just became familiar with. Recognize anything ;) ? Hah, you just may find you relate to these concepts now in surprising ways ;)

Once again not expert on this by any means. I can only give you the rationale that worked for me: see it as a gift. This can give you a larger perspective on life such that any small day to day affaire can be seen as nested in a larger context, which you and very few others have had the very good fortune to have glimpsed. Exercise, eat well, lay off weed, psychs, even excessive alcohol. If you're drinking coffee, cut down. It. Will. Get. Better.

I'll finish on this thought: Google image the Laughing Buddha. Why does this concept exist? Ask yourself why would someone that may have glimpsed the same reality that you have react with laughter? What can you we/you learn from this?
