After posting my question about my metformin last week I called my doctor about it and still haven't heard back from her. At this point I'm ready to move on from her and go someplace else but with my insurance(Tricare) I'm not sure I'll be able to. Ugh...so frustrated.

I would, asap. My dr always responds within a couple hours or her medical assistant does.

That must be so frustrating for you. :(
 I would definitely call your insurance company and see what other practices are options for you. if I remember correctly from your revious posts, this doctor hasn't really been giving you a lot of information or direction. With somethng this important and (possibly) expensive I think you deserve a doctor that is more involved. This journey can already be a rollercoaster without throwing in a doctor that you don't feel comfortable with or have confidence in.
Good luck!

I agree - An unresponsive doctor/nurse team is a bad sign and going down this road, it is the LAST thing you want to have!!!!!  My doctor or nurse calls me within an hour or two of me leaving a message.
