Pokemon Black - Nuzlocke challenge

B/W are designed so that trainer battles are more plentiful and involve fewer (nearly all trainers have only 1-2 Pokemon) but higher levelled pokemon that are actually meant to do some damage to your team. Random encounters are much weaker than usual and provide very little experience with the modified experience system and can be skipped entirely except for to catch the Pokemon you want. Oh, and both your rivals hound you incessantly and you pretty much have to fight them after every gym. It'll definitely be a different and more difficult experience doing Nuzlocke in these games.

There are doctors halfway through all the routes to heal your Pokemon (after defeating them). How do you propose dealing with them?
