Sulfamethoxazole-Trimethoprim and chills

I was prescribed this for a UTI. I took ONE pill at 7 PM and by 8PM I was vomiting profusely and having diarrhea at the same time. I had a horrible headache and body aches, chills and probably a fever. Day two I feel exhausted and still have a horrible head ache. Unfortunately it is a holiday week end and I must wait to talk to the doctor until Tuesday about the UTI.

I had strep throat, they gave me erthromicine- sorry about the spelling- I took it for two days, the worst two days of my life- I threw up constantly, couldn't sleep and gas like you wouldn't believe. Went back to doctor got sulfameth /trimethoprim. Have been taking it for 9 days, twice a day, almost done with the perscription and broke out in a huge rash. My internal temp is very hot but I get the chills and my throat muscles hurt now. Not like strep on the inside but when I turn my head- this sucks!
