A decent dose of zyprexa for even just a few days will beat the **** out of mania.
Seroquel would be option number 2.
Risperdal, jmho but not a good clinical idea.

That you are sleeping is excellent and that in itself is imperative to level out.

Be cautious of long-term use of APs. There is minimal to no clinical evidence that they are effective maintenance, lest severe, severe cases.

Mood stabilizers, yes. Likely imperative.

Don't overlook behavioral work too. It is critical to have exercise, nutrition, social supports, and daily structure that includes sleep hygiene, regular hygiene, clean clothes, clean house, etc as part of the picture. Small goals can help with that, and they will snowball to your benefit.

In the absence of those things, the likelihood of clinging to an AP is much higher, whether that comes from you or pdoc. But yes, as some have said, it's highly likely a mood stabilizer is needed long-term.

Try to space out the cigs a little bit too. I understand that situation really well. Not the time to quit or even consider, but space them out a little bit better and you can do that with awareness (which you already are aware that consumption has increased which is the first step). Fewer cigs = slower metabolism of meds.
