I reluctantly took antibiotic for an acute sinusitis with a high fever; first time in more than 10 years. Unexpectedly, it took away - while i was on it - some of my most disturbing symptoms. I became no longer "over stimulated" , and could sleep thru the night. Though it also made my thinking foggy. Now i'm doing a fast taper and seem to be getting withdrawal symptoms- loads of muscle aches and the overstimulation stuff i think starting to come back, though not fully yet. Was not expecting this.
