well Sarah said it all. i only used sorbolene (told be radiologist), i showered with it and then kept putting it on, i didnt have any problems, just a bit of redness, but like we say everyone is different, i was tired but found if i lay down for 20mins or so i was ready to go again, this is when we need to listen to our bodies, and not push the barrier when tiredness sets in, even when radio was finished, it took me a couple of months to get back to semi normal as far as energy was concerned. good luck, and please let us know how you are doing,.
