Thank you both for sharing your experiencing. Yes I, too, seem to be reaping some immediate benefits from lithium within the first few weeks even! And the Zyprexa hasn't made me hungry til now. I've been on it a while and only now has my appetite come back but I think that's due to the lithium's efficacy for getting me out of the depression (which was rendering me sans appetite). Anyway, TY both so much for replying.
