have lived w/bp2 for more than 35 years and am now having difficulty with insomnia and especially the racing thoughts at bedtime, keeping me awake. ambien puts me to sleep but it doesn't take away the racing thoughts. my pdoc wants me to up my dosage of seroquel at bedtime to 3/4 of a .25mg. tablet. am fearful of weight gain so i only take a 1/4 of a .25mg. tablet which really doesn't help w/the racing thoughts. any input would be appreciated.
