I have been on this Acetazolamide medication which i bought here http://www.internationaldrugmart.com/acetazolamide.html since I was 27. They diagnosed me with what you call a fluid tumor on my brain, which causes to much pressure on my brain which then causes migraine headaches, really bad ones. I lived with them from the age of 17 until they did a spinal tap and found out I had to much pressure. I have been on this medication ever since. I am now 51 years old.
