Because of a leg infection, I have been taking prescribed Sulfameth for a few days. on the second day I experienced cold sweats and vomiting. Since then I have been experiencing a general dizzy or disconnected feeling and a nightmare-like feeling before and during sleep. My sleep patterns have been altered in general. Perhaps the biggest hit I'm taking is my irritability which is off the charts. I've never experienced anything like this. The depression is horrible and this medication needs to be discontinued if there truly are substitutes.
