this was one of the first things I noticed when my partner was diagnosed, he can't deal with stress like he used to. He was such a cool calm person before, now if someone really gets to him, he can explode! He's better now, I notice a huge difference in his stress levels if he's not had enough rest or sleep, particularly if we have a late night over the weekend with friends.
To manage his stress especially when he gets home from work I give 5HTP and GABA
No side effects like SSRIs.
