Yes, I've experienced this as well, not being able to sleep due to the sensations. Its kind of a snowball effect, the more it happens the less I can sleep but the less I sleep the more it happens. I highly recommend getting a metabolic panel and ensuring you are keeping up with vitamins. The more regular I am with my iron, vitamin D and B12 the less this sensation happens. Even if you are barely within normal range, it might be your body needs you to be in the middle of normal range and will operate better when you are. I do not take any medication to assist with sleeping.
