Gargy, I'm in the same boat. I've been switched back to regular metformin after being on XR for a while. Tummy pains and stomach upsets galore! The only thing keeping me slightly sane is the iron tablets I've been on. Also with the pains from IVF stimming... ARRRGGHH!! I'm definitely going to be requesting the XR metformin again when I next see a doctor.
