I think I need to go back to my doctor....I've now been taking propranolol 80mg for 2 weeks and I'm almost constantly feeling nauseous, am totally drained of energy, having around 2 hours less sleep every night, waking at least 4 times a night, putting on weight.......although I haven't had a migraine for over a week, I'm not sure it's worth the rest of the symptoms! Does anyone know if they're likely to lessen if I stay on the drugs?
