I have noticed a very clear trend. If i eat any junk food, the next day I have full blown depressive symptoms that dont subside until 24 hours of fasting.

The same happens if I drink 1-3 light beers. The next day I am extremely depressed.

This isnt all in my head either , because I wasnt looking for this link. I was trying to ween out foods that I am sensitive to, and over tons of trial and error and bringing awareness to my habits, its clear. If I eat anything other than whole foods or consume trivial amounts of alchohol, i can count on being extremely depressed until I fast and its out of my system.


What underlying condition may be causing this?
