if your father is Bi-Polar than 2 or 3 medications is pretty normal especially if treatment is new and can include anticonvulsants, like Depakote, anti-depressants, mood stabilizers, even the old school drugs like Thorazine and Lithium(I'm on that, the Lithium, not the Th) but i've been on EVERY drug, Wellbutrin to Lamictal to Pristiq(I'm on that to, its really, really new and is being used to treat Fibro as well). And yes, anti-depressants are a land mine waiting to happen for alot of Bi-Polars especially like me and your dad who tend to go Manic at the drop of a hat. Addiction also tends to run high with All the Bi-Polars(not asking, none of my business)it can make the medication go-round alot harder
at least it did for me. I hope any of this helps, and I would ask about
sleep, i had medication resistant insomnia for like 30yrs and I know that would set me off into a mania as well. Hang in there, the rewards are worth it, you can ask my kids(grown-ups).
