What's the big deal? The health department in Canada recommends you take the malaria pills. They are relatively inexpensive and most drug plans pay for them. If I remember correctly, you take one pill the week before you go then one pill a week while you are there and then one pill a week for a couple of weeks after you come home. Although they are bitter it is just one pill a week!
they are not just bitter as a pill, they usually provide also with sometimes very bitter sideeffects.
many Malaria Meds are highly adviced to NOT Combine with SUN and Alcohol and several specific kind of foodwise alimentations.
to not act accordingly to the recommendations while taking malaria Pills/Meds leads to the often published Topics about Food Poisenings, because People usually do not blame their Body's reaction on the Meds they took together with getting a Tan on the Beach and some Tasty Drinks at the Bar, they blame it on the Food then.
read carefully the long list of advices in the Pack of those Pills and talk to a professional Med about what can be consumed while under the influence of the Meds and what not, and what the sideeffects are , specially when not acting accordingly to the recommendations.
I don't know many visitors to our caribbean Island who have no prob to stay away from the SUN!
cheers
