Force yourself to go to bed at the same time every night? Even if you just lay there and meditate in some way? When my mind is racing at bedtime--I take 1/2 a Xanax (it is .5 mg--I have taken a whole one maybe a couple of times a year). Also, when our thoughts are racing, it is important to just force yourself to do less (post less, don't work overtime, don't start writing novels or clean the house for hours and hours)--rather, take relaxing walks in nature or anything else that forces you to slow down. If that doesn't work--call the doc on Monday?
