Hi, just been diagnosed a couple of days ago with type 2 diabetes. I have been put on Metformin 500mg three x day, gliclazide half tablet twice a day. Tritace and Simvastatin tablets as well. Is it normal to have diaohrea, and also I have a funny sensation over my arms and legs as if they are slightly tingling, it is not sore I am just aware it feels different, also the muscles at the back of my legs feel tight. Just want to know if this is normal until I get used to the tablets. Many Thanks, Donna
