For those of you who benefit from an atypical anti-psychotic, do you think it is better to take a small maintenance amount every day, or a larger (safe) amount as-needed?

Unfortunately Zyprexa is starting to cause weight gain, but it works really well on many of my symptoms. I am contemplating just taking it on rough days, whenever, since it doesn't make me drowsy. Maybe that way I can still get its benefits without too much weight gain.

And of course I will let my pdoc know. I haven't taken it in two days and feel fine. But if symptoms start coming back, I can pop it for a few days and be back on track.
