"took this for the first time last night. 100 mg pill. i went to sleep within 30 minutes, but i woke up 2 hours later and took a 50 mg pill to go back to sleep. i woke up 3 hours later because of how dry my mouth was. i had to put a wet towel in my mouth to go back to sleep because of how dry my mouth was. i went back to sleep thankfully and woke up 5 hours later. so overall i got 10 hours of sleep. it puts you to sleep but i&#039;m having a lot of side effects - stuffy nose and dry mouth while i&#039;m sleeping; i have now been up 4 hours and still have a headache and am somewhat dizzy. i&#039;ll give this a week and see if the side effects go away. will see what happens."
