Acetazolamide
"I'm 28 and I was diagnosed with  Pseudotumor  a little over two years now I've had a VP shunt an LP shunt  and multiple lumbar punctures,  I've been taking  Acetazolmide  and I've had no side effects so far...  but I'm still having really bad headache's and swelling of my eyeballs,  so yesterday my neurologist decided that instead of taking two  pills in the morning and two pills at night,  I'll start taking three pills in the morning and three pills at night.  I just want to feel better!"
