Upcoming trip to South Africa

After relapsing a couple of weeks before my planned trip to South Africa and having to cancel it two years ago, I finally feel well enough to go this year in November. I'm going with my family & some friends of theirs & we'll travel from Port Elizabeth to Cape Town. Would love to connect with some other MSers in the region & I like to be prepared for whatever might happen, so I'd love some advice on neurologists in the region if MS decides to act up during the trip. Also, is Sativex/THC legal to bring with a doctor's note? What should I consider while preparing for the trip? Thanks in advance for your help! <3
