I took my first dose today, and have had my prescription for 2 weeks! I have had severe reactions in the past to various drugs and am quite fearful of any and all new drugs. About 35 minutes after taking the pill the road looked kind of crooked to me I would almost describe the feeling as dizziness but my balance was not affected. Should I be concerned about this or is this the kind of dizzy they mean when they say "contact your doctor immediately if you experience dizziness... "?
