TMR .... I am not p*ssing about here.
Get to your doctor .... what you are describing is the classic onset of Type 2 diabetes. Those are exactly the symptoms I had when diagnosed two and a half years ago and it was those symptoms that I was happy to ignore until the GP spotted them. In fact I was quite pleased at losing weight.
Get it sorted now or you could be looking at Heart Attacks, Amputations of toes/feet/legs due to gangrene caused by thrombosis etc. No joking mate. Forget your fear/dislike of Doctors and get your arse down there NOW!
