I have been on Metformin for 6 weeks now after being diagnosed a type 2 diabetic. I have in 6 weeks lost a total of 1st 9lb in weight. I am a long time asthma sufferer. My GP moved me to the slow release Metformin about 7 days ago so the stomach pains I was getting before seemed to have gone. I am finding I am still every tired, poor concentration, blurry vision ( had eyes tested) and sometime I get sweaty. I rarely feel thirsty and I am not weeing much during the day or getting up in the night. My Vitamin D is non existent and my Iron levels are low. I am finding all this and a full time job in management a lot to deal with and find myself getting upset or crying at the drop of a hat. I am finding it hard when I need to take steroids for my asthma. I am aware of the side affects on my blood sugar. I just want to start feeling better not just a blubbering mess!!
