imho total sobriety for proper integration. don't eat supplements or haze your brain.
what has worked for me:
daily stretching for circulation (look up guides online, 30 min is good start), strict sleep schedule (not too much, waking at the same time each day), time in sun (20min+), time around other people (social interaction helps you get out of your head).
diet of brown rice, vegetables, 'complete' protein powder, lots of water.
keep busy, productive, and focus on the moment.
choice in music/media can play a role. a book that's easy to read gives your thoughts direction, though if that's too much then clearmind to something non-stimulating like shoegaze or popular country music to give your brain a break.
enjoy.
