Re: Is it worth staying on beta blockers??
I advise to check with your dr. He can change the doses or switch you to another BB.
I am on Carvedilol without side effects but every one is different... now some of your concerns..
1) While in BB you need to forget your previous exercise HR. As you describe it, it will be very difficult to achieve them. If you need to reach that HR then tell your dr, so he will take you out of BB.
2) For the gases, I take any OTC pill with 120 mg of simeticone.
3) For constipation, I take an small glass of concentrated prune juice in the morning (sold in pharmacies).
