Remember that the barrage of IV meds create havoc with our immune systems, basically for about 2-3 weeks after IV's i find that i don't have an immune system and will pick up everything that is going around. So, take loads of supplements that enhance immune response while on IVs and for at least a month afterwards. I use high doses of garlic, fish oil, magnesium, vitamin C, iron and probiotics and as Diane said, avoid public places and children (walking petri dishes <img src="i/expressions/face-icon-small-happy.gif" border="0">) and use hand sanitiser every time you have been out in public touching supermarket trolleys or ATM machines etc. It is also good to get into the habit of never touching your face, especially your eyes and nose, as this is how we ingest viruses into our systems.
