If you need Seroquel to manage your bi-polar disorder, and you don’t have insurance (which I gather is the real problem), you may be able to get some assistance from your local community mental health clinic. But you may want to consider other medication options.
Seroquel is a powerful antipsychotic drug with serious side affects. There is a $593 million class action lawsuit in progress because Seroquel (AstraZeneca, Zyprexa, Risperdal, Clozapine or Clozaril and other drugs in the same class) can precipitate diabetes, pancreatitis, stroke, and tardive dyskinesia (uncontrollable tremors). It also lowers your blood pressure and can leave you feeling like a rag doll.
Taking Seroquel just for sleep is serious overkill. (By comparison, melatonin, Benadryl, NyQuil, and Omega 3 are only slightly more sleep-inducing than chamomile tea.)
Depakote is probably the least toxic drug you can take for bi-polar disorder—if it works for you—and much easier to get, since it has gone to generic and because it is good for so many different problems (chronic anger, migraines, seizure disorders, racing thoughts, etc.). Depakote is mildly sedating, but it multiplies the effect of benzodiazepines, like Valium, if you still need something extra for sleep.
