I'm on medication for OCD & I take a prescription sleep medication, too. I want off the sleep medication because it makes me drowsy, but yet I feel like I'm addicted to it; it helps me sleep even better. My psychiatrist won't let me off of it & says it's not psychologically addictive.

I see her again next month (I'm overdue for an appt. because I'm an hour & a half away at school, which is obviously over for the semester), & I will bring it up again.
Please don't just stop taking it without talking to your doctor/psychiatrist first. Believe me, I'm tempted to do the same but I know I shouldn't. I can relate somewhat to your post.
