I have important exams very soon and recently my brother, who is a heroin user, has been in hospital. Not surprisingly my body has responded with some rather worrying anxiety attacks where I get chest tightness and palpitations and basically feel like shit. Gp has prescribed my beta blockers at the lowest dose of 10mg 3 x day but they also make me feel like shit! I feel sooo tired on them and yesterday i fell asleep for the whole afternoon which is just completely impractical as I need to study for my exams. However if I don't take them I can feel my chest tightening up etc. I tried taking half a tablet at each dose the other day, but I still didn't feel great, think I was still getting some anxiety symptoms mixed in with the side effects! Part if me thinks I should try to persevere as I do not want a panic attack in the middle
