am 66 female bp1 and the last year i've had terrible insomnia w/those darn racing thoughts. ambien quit working and the pharmacist told me ambien puts you to sleep but doesn't keep you asleep (which is my problem) and it does nothing for racing thoughts. pdoc said a little bit of seroquel plus klonopin will do the trick...and it does...sleep plus no racing thoughs...and when i had to change drs. due to now being on medicare, new dr. prescribed the old fashioned valium. wow. sleep and again no racing thoughts...so 1 nite i take a tiny piece of seroquel and next nite valium and for really bad nites, seroquel and klonopin.
