It's possible. One of my German friends said pharmacists are in demand, especially in Brandenburg, but no way will I live in Brandenburg. The number of towns within a reasonable commute from Berlin (30-45 minutes by train, preferably accessible on a Berlin ABC transit pass) is pretty small.

I still have no idea what would be required for me to work as a pharmacist there: whether I'd have to go back to school and learn from scratch, or if I could just spend a year as an apprentice in a pharmacy and then sit the license exam. I really don't like license exams; if I sat down to take the NAPLEX today, I'd fail. (Most of us would, after a few years of work, when we don't have everything we learned in school fresh in our minds.)

Ideally, this writing career will happen by then. It doesn't pay much, most likely not enough to be proof that I can support myself (currently E10,000/yr). I don't know whether you can get multiple visas (ie one for freelance/self-employed writing, one for part-time work either through an employer or SE). http://www.toytowngermany.com/forum/index.php?showforum=180 has lots of discussion on visa issues, and http://www.auswaertiges-amt.de/EN/EinreiseUndAufenthalt/Uebersicht_node.html is the official site (English version).

I honestly wouldn't mind being a tour guide with one of the English-language places there, but you have to have lived in Berlin for a year before you can apply. I would need to somehow support myself, or Ben would need to find a job that can support us both. That may be the hard part.
