Message to the mods - if you think this belongs in OT then please move it - I wasn't too sure I've noticed that the day after gigs I feel pretty rough. Its not beer as I don't drink or smoke etc. We play pretty loud, and in small clubs so I'm usually within a couple of feet of my amp. I cycle a lot to keep fit so my general health is good (haven't been off work sick in over three years) What tends to happen is that we'll play on a Saturday night and then on Sunday I'll get stabbing headaches all day when I move. I feel bad from the moment I wake up. I drink plenty as we tend to end the night with some ska and LOTS of bouncing round the stage so I lose quite a lot of fluids as sweat. So everyone out there - whats causing this ? Anyone else suffer the same or is it just me ?
