Weight gain

It does sound like the steroids make you gain.  For me I lost weight while on the 2nd half of chemo (Docs & hercepton) and continued to lose it on just hercepton, even though I was eating like 2 horses all the way through.  (I have never eaten so much in my life).  As soon as hercepton ceased I gained all the weight back on very quickly.  I am now exactly what I was before treatment.  My Onc still tells me it was not the hercepton though, and I really don't want to have to back on it to prove my theory correct.
