Weighted blankets

I was wondering if anyone on the forums has used or currently uses a weighted blanket?

I have read that they can be very good for relieving anxiety and can even help to improve sleep, but I am a skeptic when it comes to the marketing hype.

I am interested to hear your experiences and whether you think they are worth the money as they don't come cheap!

The reason I am considering one is due to my anxiety levels being very high for a prolonged period of time now as well as having to deal with poor sleep.  I have tried medication and it hasn't agreed with me so I am getting desperate for a solution, especially as my health is starting to suffer and I am becoming very run down.
