No
I used Malarone when I went to India, I think I had to take them for a week before and a week after or something like that. My trip was a fortnight and I was absolutely fine. The only nausea I experienced was after I got back, on the final two days of taking the tablets, but I think it was well worth the expense.
Definitely take Marmite with you and eat as much bread as possible, as the yeast thing does help to some extent.
The nausea was nothing to do with the Desperado's you were drinking then

Is there anywhere locally that sells them? Only ever seen them abroad!
