Acetazolamide
"This drug has not helped relieve pressure,  headaches or Visual Impairments in my case. My vision continues to go in and out without notice, waking up everyday with a headache and continue to have one well into the late evening before bedtime. The side effects are awful!  I have lost 29lbs in THREE weeks! I am unable to hold anything down, everything tastes nasty or like I'm eating pennies. Constant fatigue and restlessness. The prickling in the hands and toes, not to mention the constant nausea. Every case is different. It's not working for me but could for someone else. I cannot tell anyone to NOT take a drug or TO take a drug for IIH. Because every case is different, everyone will see different results."
