Heeyy, I am back after the winter hibernation!
Careful with those Beta Blockers folks! They are used for many different things such as heart palpitations, stagefright and migrain.
I tried them after experiencing some uncomfortable, but not dangerous heart palpitations during a very stressfull Christmas. Then I got REAL depressed REAL quick. It was scary. Fortunatly I was aware enough to google experiences and side effects, and concluded the "harmless" Betablockers were the cause. I got better again rather quikly after quitting.
So here is my experience, should you need input.
