Hi folks Since Saturday morning I've been suffering from dizzy spells. If I move my head suddenly it seems to take a second for everything to catch up with the physical movement and then I feel vaguely sick. This has been coming and going since Saturday and doesn't bother me at night. I've not been drinking or eaten anything unusual. However due to an error at my doctors I've run out of Avandia and probably took my last one on Thursday or Friday. Could this cause the dizzyness or should I look for another reason?
