ya my pcp doesnt knnow much either and usually i do have them call my cf specialist but he is wanting to take things into his own hands i guess and really dont want to listen to anything i say...and just a few hours ago i dropped all the way to 39...and they gave me d12 and it went all the way up to 266..thats how un controlled my blood sugars are..and i really hate when they drop cuz it affects me horribly bad
