Metformin..you want to know,? well here goes, they tried me on the rubbish some 14 years ago, diarrhoea, throwing up, stomach cramps, muscle ache vision disturbance....after 1 pill. Anyway a stupid doctor lied to me 6 years or so later, and said they wanted to try a new pill and wanted me to be in hospital to monitor. Pill 1, serious cramps, diarrhoea, muscle problems, visual disturbance, next pill, now cannot focus, cannot eat, having dificulty in moving, in extreme pain all but screaming out. They gave me morphine, third pill, what with the morphine, stomach cramps,sickness etc managed to get sitting on side of bed. could not call for help. No more pills. next day nurse let me see what they had given me ...bloody morphine, still cannot focus cannot use glasses, cannot focus even on a TV. Took six weeks before I could ride my motorcycle, 4 weeks to drive my car at about 40 mph max, could not read until 6 weeks. To think that I was taking morphine for a week after three of those poisonous little pills. They would not let me leave the hospital for 3 days after taking the poison. Other symptoms are severe vitamin B12 loss causing clicky finger etc (that however also maybe a dibetes problem),false heart symptoms, total loss of libido which after several years has never returned. Sure take the ****, however it is possible the problems may be worse than the insulin which I have been on now for 14 years. I have problems with that, even now found that chest pains are relieved with desloratidine. Have been taking that for over 10 years. My dad had problems, yet the medical will not listen, he ended up on porcine due to various problematical pains. They will not try me on that, oh no, just keep increasing the insulin, 46 morning, if I eat midday, 46, if not nothing, evening 60-66 depending what we have and 44 going to bed. BS am 5-9 normally evening normally 5-7.
