Thanks Paul for your fast reply...
Usually in January Buenos Aires gets really hot weather wise. Temperatures could rise up to the upper 30 degrees, some times nearing 40 C, but that's an exception. The good thing about january is that a lot of people goes off to vacation somewhere else and the city is not that crowded.
At night feels much better. So don't miss the Tango shows in San Telmo.
Too bad you wont be able to taste some of our very good red wines! And be careful with the "parrilladas" (a lot of different kinds of meats on a single serving) some are really high on fats.

I'll probably be in Buenos Aires by then. If so, I could drive around to show you the city. Although, chances are I could be flying to somewhere in the world to get the meds. Australia, China, Bangladesh or India by then.
I really hope that twelve weeks would do the job. I can't wait to regain my energies. Until now I've been loosing strenght and close to give up hope. This forum has been an injection of new life for me...
Best wishes and if there is anything you need to know about Buenos Aires, just let me know.
