5 mg had problems with that also, the problems that I was having was my BP would go down to 95/55
and I would get so dizzy
and lightheaded all day long and was unable to live a normal life, so was put on Carvedilol 3.125 mg, I am doing better with this except that I have asthma and people who have bronchial disease shouldn't take Carvedilol it has a tendency to weaken the lungs, I have been having a terrible time with my asthma as of late, it could be the meds.
