Hello Michael, I've been on Trulicity for 8 or 9 months and it's been good for me. Like you I couldn't tolerate Metformin. I was running at about 15 trying to control BS with diet and exercise after I finally gave up on the Metformin and now I'm getting readings of 6s and 7s. I can't say I don't have ANY side effects. Every now and again I feel very sick, never actually been sick - the feeling only lasts for 10 to 15 minutes and then I'm fine. Seems like a good trade-off for lower figures. Hope it works out for you, good luck!
