I'm fine before my workout, but right after or during my workout, mood drops.. I'm a total mess for the next 2 hours. I become depressed, anhedonic, and anxious to the point of being suicidal. This doesn't happen if I only eat vegan. But if I've had any animal protein during the day, I'm a total mess after my workout. I can't be a vegan, for many reasons. I tried it for a year, while I wasn't depressed, I was lethargic and didn't want to do anything.
Can this be excess or lack of serotonin from tryptophan uptake which increases during workout? Does increase uptake increase then depletes serotonin or maybe increased serotonin is as bad? What other neurotransmitters are released during exercise?
