Forgive me for not understanding this but why were you taken off lamictal? I understand why the Pristiq was changed out but I can't help but think that after being on lamictal so long that going off it would be likely to really mess you up. I don't know how long it takes for your body to really recover from that change but it can't be easy for your brain to suddenly be missing chemicals it's had for years.

If there wasn't a specific reason would your pdoc (and you) consider resuming it? It seems like for people who can tolerate it it's such a basic med and generally a helpful one. Depression symptoms without it would be expected for some time.
