Has anyone had any weird reactions to MTX injections?

I'm trying to get in to see my rheumy this week (had a bit of a phone war with her assistant today) because I am not any better.

I DREADED giving myself my injection today because I'm still not feeling good. I didn't want it to be worse! The last time I remember feeling my halfway decent-ness was before my last injection however I'd had a sore throat for a week before that and with the flu floating around work I didn't know if it finally just hit me.

I keep getting dizzy, I feel SO run down, I have trouble walking without wanting desperately to go lie down (we are not talking long distances here), I get nauseous from being dizzy, I could sleep all day if I had the time.

Has anyone else ever had this kind of reaction?

I need to take a few weeks off, I wonder if my doctor would make that happen ....
