Herceptin- from three weeks to weekly??

[mts]

I find as I read theses threads that many of us are beginning to manifest more severe symptoms the longer we take Herceptin. I really feel I need to stay on the drug, but when I feel like doo-doo; I can't help but wonder what may be next. I can handle the itchiness, the blotchiness, the weight gain. My MUGA's so far are great. But nausea... I hate it.
These last couple of Herceptin infusions have left me a bit nauseated for several weeks. I am receiving the Herceptin every three weeks and I know that the large dose may be the culprit... I was wondering if anyone has had a "bit" of nausea from being on Herceptin.
I've been on it since Aug-05. I'm also on tamoxifen.
Has anyone felt "better" after they switched to weekly Herceptin? Anyone on bi-weekly?
