I feel "yucky", temp is 97.3

Dear friends,
Yesterday was my 4th Hereceptin infusion, only Tylenol for premeds as I did fine on 12mg of Benadryl last week (am on weekly schedule) so I decided to skip Benadryl altogether. I finished AC/Taxol dose dense May 31st,2005.
I had the mosy awful chills last night and upset tummy this morniing. Went to work and felt progressively "yucky" alll day. temp is running very low (was 96.9 last night)... feel kind of "fluey" (lightheaded etc). I thought that I was passed the point of having a reaction?
Anyone else experience this?? Any suggestions???

ARGGHHH!
Thanks ,Soccermom
