Hi, I am 44 and developed diabetes in pregnancy seven years ago. After pregnancy I was borderline for about five years but diagnosed and put on three Metformin per day about two years ago. On my last checkup in May this year my blood test had revealed sugars of over 7 so my metformin was increased to four per day. However more recently I have felt really rotten. I feel tired all the time and sick, I can be really short tempered and have little energy past 3pm. My first fasting test of the day can be between 9 and 15. My tests 2 hours after eating again can be between 7 and 13. Sometimes I have rapid pulse. I am wondering at what stage you need to go onto insulin and would I feel better? I just feel I have little control of this at the moment.
