I'm really not sure if my problem is the same. I too feel mine is OCD related.
It wakes me up in the middle of the night, and keeps me up.. like now. Its just about 3 am and I have been up for like 2 hours crying over this nagging urge. Its almost like restless leg syndrome, except in my ankles.

And it bothers me so much I cant sleep. I was taking meds for RLS and other stuff, to help me sleep, but I had to stop taking them cause I am pregnant. I lose so much sleep now, its literally driving me nuts. I have a 3 yr old, and I have to take him to school in the morning, and by that time, Im just so exhausted I cant think straight. My husband is on deployment for the next couple of months, and I feel like Im going to lose my mind. Its getting so aggravating, I dont know what to do. I tell my doc about it, and they just look at me like Im crazy. Any suggestions??
