i hv been diabetic for last two yrs and started with Glucophage XR 500mg once a day. then moved on to normal Glucophage 500mg once a day and then 500mg split in to two twice a day. recently i was suggested by a senior doctor to increase the dose to three times 500mg thrice a day and also start Crestor 10mg once a day, though the reportes seem to suggest the levels are within acceptable range. i hava a heavy/dizzy/nauseatic feeling most of the time since i have increased the dose.
