OK, I am going back to doing neutralizing at the same time I do the vest. It will save lots of time. On another note . . . . I am doing 3% saline at the moment. Ask Infectious Disease Dr about going to 7%. He said OK that he would send in a prescription to the pharmacist. Got a call from the pharmacist saying he could not fill that until he spoke with the Dr first. Pharmacy has no one using 7% saline and he said that it should only be used in a hospital setting. So he won't fill it until he speaks with Dr. It seems as if a lot of you are using 7%. I was trying to work my way up. Is it dangerous or something?????? What are the side effects that might be different from 3%. I figure it may be somewhat more harsh on the throat. Has anyone had a problem with not being able to lose weight on saline no matter how little you eat? I do have thyroid issue and am on meds. That could be the problem. Just checking!
