Beta Blockers, Propranolol, are great for the physical effects of anxiety. I take then occasionally, the only ill effects I get, is they do slow you down a bit, can make your eyes dry. They will help you to relax. They also use them for PTSD to help to lessen the memory of traumatic events. I take the 40mg. I don't take them at night because I tend to get very dark dreams, wouldn't want to make them any worse.
Years ago I was on the 80mg slow release, but I prefer the 40mg. When I asked the Dr about overdose, he said you would have to take about 80-100 of them! Yet my aunty, cuts them in quarter because she believes they make her high!
We are all different.
If only they would hurry up and legalise cannabis! I would be in a café right now.
