pseudotumor cerebri
"Effective, but not without side effects. The first month was pretty bad - my hands, feet, and legs were falling asleep and I experienced painful tingling and cramps. My joints also had problems, and I had to wear a brace on my knee for a little while. I was more lethargic. Anything carbonated tasted awful. I couldn't drink caffeine or my whole body would feel weird and tingly. I also had to pee a lot during the first few weeks and was quite thirsty.

Over time, most of the side effects went away, and my pressure went down. My vision problems completely went away. However, a new side effect appeared after about two years - tinnitus. It is definitely being caused by the medicine, because I've found that skipping a dose makes it go away."
