"I was on this medication for about a year and a half. When I did take it I was also on 13 different psychotropic medications. As you might of guessed it was/is difficult to fully understand propranolol's benefits as well as it's hinderances. I really want to believe it helped.
Honestly no one knows how you will react to any medication until you take it and observe who you are and how you act. The doctor has broader intellect with pills and function of the brain.
Put faith in your physician and have no expectations.
