Acetazolamide
"I have been on acetazolamide 500mg 3xper day. On the first day I experienced tingling on my feet that lasted at most 5 minutes and I woke up disorientated on whether it was 9 the same night, the next night, or the next morning. I have a ridiculously busy schedule and I'm always tired so I am still unsure if I have experienced fatigue due to the medicine. Get the capsules instead of the tablets if possible. Tablets release all 500 mg at once. The capsules release little by little so you don't get all the side effects just dumped on you. With the capsules side effects seem to be lighter in intensity. Soda tastes like crap. I already urinate frequently due to my water intake. My psuedotumor symptoms have disappeared though."
