Bactrim DS and medication

I have had every side effect that the medicine states that you can have. I normally don't react to medication, but with this stuff, it is ridiculous! I took it for an infection that I had in my ear and from the very start, I felt loopy every time I took it. Then I began almost like hallucinating when it was bedtime. I was extremely tired, but could not get to sleep. Finally, the morning after I finished the prescription, which also happened to be my birthday, I broke out in hives from head to toe. I appreciate that my ear was healed, but now I have a whole set of different problems just from the meds!
