I usually try to listen to the Dr. or NP I also try to inform them on everything I am using to see if anything interacts. I give lots of advice when asked and sometimes when not asked, (I am a nurse also). I usually research on what has been advised or prescribed. The hardest to hear is you have to lose weight or things aren't going to get better. don't I know that already. I hate going to the Dr and then hear You're an RN so you already know this, no I don't or I wouldn't be here. OK enough ranting and back to exercising..................................
