"suffered from insomnia for ~5 years before being prescribed zolpidem 10mg. it took about 15 minutes to work and it put me to sleep very quickly. after ~1 week i built up tolerance and my doctor increased my dose to 20mg before bed. this gave me increased side effects - seeing double, increased drowsiness the morning after. i would also do/say things i had no memory of, and sometimes i wouldn&#039;t be able to tell if what i was remembering was a dream or whether it actually happened. overall, it put me to sleep but the side effects were quite severe. a very good treatment in the short term, but it starts to mess with your sense of reality at higher doses once your tolerance builds up."
