I don’t recall what the heck I took when I came down with a raging bout when I was working in eastern Africa...but I have not had any residual problems. I do recall staggering out of the clinic at the mine with a bag full of meds, (and a new mosquito net!) and whatever the prescribed, I was over it in about 15-days. Seems I was still taking meds for about a month.
Not fun at all!
Some of the treatment can and must continue long past symptoms have disappeared. My guess is that you had quinnine. IMO, it is the medicine from hell (until I took Larium. More on that later). It left me staggering, dizzy, hearing things, vision disoriented, etc. I had to take a medicine a half hour prior to taking quinnine in order to keep it down! It was no fun. No fun at all. Not any.
But then, I took mefloquin, aka Larium. It worked. But then a week later, it threw my BP sky-rocketing. I showed heart-attack symptoms. Further, for the next six months I spiraled downward into the worst depression I have ever experienced. Worthless feelings, almost suicidal, hopelessness, despair. The only reason I made it through that experience was God’s grace and knowing that my feelings were not based on reality but were chemically induced. I will NEVER take that med again.
