"was just prescribed this medicine (the instant -release, not extended-release) for sleep and anxiety. i was told to take 150-300mg at night for sleep. i took 150mg last night and have been half asleep, mind in a fog, can&#039;t focus, etc. all day. i&#039;m thinking i need to cut the dose back a lot. my anxiety is gone because i just don&#039;t have the energy to be anxious about anything right now. i have no idea if my sleep was &quot;better&quot; because i did wake up several times, but i fell asleep faster than normal each time i woke up."
