"i was prescribed this drug in my early teen years and it worked wonders at first. not, at 20 years old it doesn&#039;t work at all. i will sometimes have to take 2 pills at night and i will still wake up 3 hours later. i guess i built up a tolerance but i will be switching medicines. plus i would find myself in the kitchen eating every night, and one had a blender out about to make margaritas.... this is definitely not a long term drug."
