Hi all..not sure I can offer anything useful as Im a "taper newbie". The first DAY I cut my vanco from 4 per day to 2 my gut reacted. I likened it to the "battle of the spores and probis", feels like gang warfare in there. I have to believe it is just my system battling it out and this thing is simply rearing its head trying to overtake again, but then after I take my vanco it settles back down. Hopefully you have a doc that will answer your questions, mine simply says it will eventually "peter out" and my body's natural immune system will win in the end. Thats great for me - Im still young and healthy, but my God how do folks that arent so healthy survive this? So depressing. From the reading Ive done on this site, I have it mild in comparison so I try not to get too down. Best of luck and health to you all in battling this horrid bug.
