Hi everybody: I write in the aftermath of the worst vomiting & tummy explosions that I've ever had Is this normal? I've been taking Metformin for nearly a fortnight now... and can only say it makes me feel like pants. Floaty, tired, gassy, grumpy ... aggressive even. Tearful too. Not to mention itchy *scritch, scratch*. BIG apologies for having to share so much that is so very yucky btw... but I am getting worried :?
