Hypnagogic Jerk involving the Anal Sphincter?

I am experiencing a hypnagogic jerk that's a little different than the others, and it is frustrating. The instant I feel that I am going to drift to sleep, I get a twitch/contraction on my anal area, I wake up, and repeats.  The feeling is similar to the natural contraction of the anal sphincter area when finishing to pee.… I am now conscious of this and has become a vicious cycle, and have trouble falling to sleep.  I am wondering if anyone has had/have this condition? I have done some searches and it seems like something that’s not very common with insomnia sufferers.

I am on occasional .5 mg Apralozam (Xanax) right now for anxiety, but I don’t know whether it is the meds or the anxiety or withdrawal in between doses.

I just wanted to chime in to let you know I experienced the exact same thing when I took Klonopin. It was ONLY in my anal area and drove me nuts! As soon as I weaned off the Klonopin it stopped. I wasn't on very long (maybe 1 month) because of all the side effects. So I am 99.9% sure your twitching/contraction is from the Xanax since it's a benzo in the same family as Klonopin. Hope that helps.

Thank you very much for the reply.  I have been going crazy the past few nights because of this.  At least now I know someone else has gone through the exact same thing and know it is the benzo and not some physical condition I will have to live through the rest of my life. 

I have only been taking Xanax for 60 days and average about a .5mg pill every 2 days (as needed).  I am ready to get off it.  I'll talk to my doctor about weaning off.  

Thanks again!

I think that's because your muscles are in a relaxed state. Including you anal muscles . So the tablets are just doing what the are supposed to really. 😩😩

Hello,

I'm facing the exact same issue. How do you feel now? I hope you manage to get through this. How did you get over it?
