"i&#039;ve started experiencing insomnia quite severely lately. i think my plate is just too full and i&#039;m too busy that my brain hasn&#039;t been shutting off at night and i lay there feeling relaxed but not actually relaxed. anyway, my doc prescribed temazepam to replace ambien (which i was on for years) since i would lay away for 6 or 7 hrs and only get an hour or two of sleep. i really felt this medicine &quot;turn off&quot; my brain. the first night or two i fell asleep right away but since then it&#039;s been really hit or miss. i feel so calm and not thinking about anything but yet i&#039;m wide awake until 2 or 3 am (i get up at 5 am). i&#039;ve been on it for about a month now and still having trouble falling asleep. out of the 5 nights this week, i had 3 sleepless nights."
