I have recently started trying to take better care of myself and have started doing some cardio and weight lifting. I will preface that I live a kind of sedentary life (desk job and walking my dog) so intense exercise is something I’ve done pretty rarely.

I’ve noticed that almost every time I work out, shortly after I feel like I am having a manic episode (hyperthoughts,speech,easy agitation) and then the next day I usually plummet into a depressive state. 

I am wondering if anyone else experienced this?  

My only thought is that exercise is maybe making metabolize my meds differently? Or just because I rarely exercise my brain is doing a crazy serotonin dump and it’s too much for me?
