never had sleep issues w/my bp1 til about a yr. ago. ambien is like eating m&m to me and the pharmacist said that it will not stop the racing thoughts which i have every nite. 1/2 of .25mg. seroquel does the trick and recently a new dr. prescribed 5mg. of valium, an older drug. have tried .5mg. klonopin which does work and sometimes will combine klonopin and seroquel when i'm really stimulated/stressed...but so far i have found 1 night a piece of seroquel the following night a valium and i sleep well w/no racing thoughts. also started taking .5mg melatonin an hr. before bedtime and i'm finding it does make me sleepy...before taking either the valium or seroquel an hr. later.
