"i was prescribed topiramate for daily post-concussive headaches, and i also needed to lose weight.  the first three weeks were really rough, and i was unsure if i could take this medicine long-term.  i started off with 25mg the first week, 50mg the second, 75mg the third, then 100mg as my permanent dose.  i took it before bedtime as instructed, but i had next day drowsiness so bad that for three weeks i felt like i was going to face plant at any moment.  also, the nausea was so bad that i barely ate.  thankfully, both of these side effects stopped after about 3 weeks as did most of my headaches.  i&#039;ve also lost 22 lbs in 2 months.  the best part is that it has given me control back in that i eat smart and don&#039;t have unhealthy cravings."
