Sulfamethoxazole-trimethoprim DS Low Blood Sugar, First Thing Monday Morning, Dry Toast, Lack of Appetite, Sinus Infection

I was prescribed Sulfamethoxazole-Trimethoprim DS for a Sinus Infection. I am prone to having them, so I figured they would just prescribe me the usual Amoxicillin. But instead I got this, and I wish I didn't. I just finished my prescription, and I am praying for sleep. I have gotten a total of 24 hours of sleep in 10 days!!!!! Mind you I am a full time Nursing Student and a single mom to a 2 year old!!! Sleep is extremely important to me!!!! Minus the lack of sleep, when I actually do sleep, I have been having some of the most "weird" dreams!!! Dreams of things that I can't even begin to find words to describe. Vomiting at least twice a day, dehydration, a complete lack of appetite, the shakes; which resemble someone with low blood sugar, dizziness, puffy face, and diarrhea. I seriously have no idea what the doctor was thinking that was filling in for my regular PCP, but I am filing a complaint at their office first thing Monday morning regarding the prescription. Every time I called into the office regarding the side effects, they told me that it was just normal side effects, and to continue to take my medication and to try and take it with "dry toast" to help keep it down. Dry toast isn't going to help when you can't even keep down your own salivia!!!!!
