I'm on propranolol and it's just slowed my heart rate down a bit. I think one of the side effects is occasionally fainting which is linked to the low heart rate and low blood pressure mentioned in previous posts, but that's something I have never experienced in the past and hopefully never will!
My counsellor says to think about coming off them in April / May after the clocks go forward and the days get sunnier cos apparently that's the optimum time to come off meds.
I think I can definitely cope without them as I've found my problems to be mainly in the mind and not the body.
