I've been on Metformin since 2007 and have spent time in hospital due to severe dehydration and diarrhoea I was going to the toilet up to 12 times a day when I told a doctor they said some people do go that many times so I battled though, eventually it became a massive problem again I wasn't able to leave my house for 5 weeks I had all sorts of tests to see what virus's I had, apparently none!! Then I saw my Doctor and told him I could not go on it was too much, I was getting 3 minutes warning before Armageddon, he checked my diet, then said "do you take metformin?" "Yes" I said well stop taking it he said 12 hours later peace and calm broke out I hadn't been this well in 9 years and I continue to be well. Metformin was ruining my life and I didn't know it!!
