It usually happens in summer yet never the much less in winter too.
I sometimes enter a trance-like state of mind of being "over worked mentally" while working out.
It becomes too stressful that I have actually visuals-like experience like I would certainly space out and do not hear or see at all and afterward I feel rather angry or aggressive after my workouts. Now, I tend to feel the same peak of aggression in early morning, so I started to talk long walks.
I do not use much really various other than multivitamins, acidophiles, etc. I do not eat any protein whey, yet I sometimes use l-tryptophan at night to make me sleep and some green products when I could drink it.
