Looking to see if anyone has had any experience with the effectiveness of Metformin versus Metformin Extended Release. I am a T1 with a great deal of insulin resistance so I take this med along with insulin from my OmniPod Pump. Over the past year, I have taken both the regular Metformin and the Extended Release versions and seem to be having much less luck with the Extended Release keeping my BG numbers down. I am going to be in touch with my Endo to look into changing back to the regular version. Any thoughts or experiences that you could share would be greatly appreciated!
