Herceptin hangover

[stayingstrong]

I know this is an old thread but I was somewhat happy to see it considering I have been feeling so much of what you ladies mention. In addition to feeling tired, joint and bone pain, starting to have what appears to be arthritis in one finger (I'm only 46 and never had any signs of arthritis or bone and joint issues) and stomach issues with each successive herceptin infusion (I have had 13 so far), I've noticed that I'm just more down and not myself for the week following, then I start feeling a bit better as the next two weeks progress just to have another treatment and start it over again. Does anyone else experience that?
