lyme disease
"Medicine was effective to a degree it ameliorated muscle pain, joint inflammation, and mild-to-severe headaches.  Inflammation/rash in upper body area (predominantly on the back) occurred within a week of beginning three-week regimen--persisted until end of ingestion; though it faded in both discoloration and swelling, as well as itching, over time.  Some blurred vision and intestinal discomfort occurred, but was not debilitating to any significant degree.  While fatigue was lessened somewhat, it did not preclude a general feeling of somnambulism or sleepiness; which my physician says may persist for a few weeks or even months. Overall, I'd rate this as an effective medication against the Lyme Disease I developed."
