I was originally put onto metformin just over a year ago but it was the immediate release stuff and for the most part it was ok but then I eventually started having digestive problems and for great periods stopped taking it because I was home alone due to unemployment looking after my two daughters and couldn't afford to be rushing to the toilet constantly. In November last year I eventually asked my doc to put me onto metformin SR because of the problems and so far I have been ok. My original dosage was 500mg 3x daily so my doc put me onto the same dosage of SR to be taken once with my evening meal. Now here is where the question comes in, has anyone been put onto SR and started losing weight withought trying? I wouldn't say I eat badly, but since I started back to work I have been eating more regularly and in greater quantity and the amount of high carb and fatty foods has been creeping up, certainly I would have said my calorie intake is probably more than it should be but still the weight is slowly coming down. Now you might think this is a good thing but what really has me worried, is that for as long as I have been on metformin (most likely just a coincidence) I have problems in the bedroom, in the sense I stand to attention but the little solder just doesn't do anything else no matter how I try but more recently I have developed an ache in the groin (which I am being referred for a scan to determine what the problem is) and perhaps naturally my concern is that it could very well be the Big C when combined with the weight loss. Has anyone else experienced anything similar?
