Someone responded to my most recent post about antidepressants by asking whether I'd tried non-Lexapro meds. The short answer: Yes, I gave Celexa a whirl, and it seemed to diminish my verbal abilities. This was upsetting but not entirely unexpected, as I'd been warned many years before that some SSRIs have that effect.
Lexapro is ridiculously expensive at roughly $100 per monthly supply, but I'm reluctant to mess with other meds when this one has worked, on the whole, so well. I also know that my weight gain is almost certainly due to a variety of factors -- Kibbutz food, waves of mild depression that elude the drug, etc. -- so I'd be more likely to drop meds in general than to go searching for a "better" one. It probably doesn't get a whole lot better than this.
