I was testing Propranolol since begining of fall and it's the most promising thing for me.
Turns out green tea particulary messes me up ( I become shaky inside, heart starts pumpin', prone to joints pain, any emotional situation pushes me off limit to akin adrenaline rush at first seconds of fright, but prolonged in time, bad bloodflow, shortness of breath etc.)
So if I have a cup of green tea only Anaprilin can help me after (it doesn't go away FULLY on it's own). Usually I would take 20mg with wheat bakery (or with cheese in addition- even better) then sit at home next day, since I can't walk too much after anapriline, and then ejaculate in the evening. After that I good to go, can walk normally and exist without any "adrenaline" symptoms.
Temperature changes can still mess me up, but it's managable, I didn't happen to test stress resilience in extreme situations but casual situations are no problem (unlike in the green tea phases). I also yet to test waking up before fully rested (with alarm clock) on this scheme.
