Tokunbo,
your post and Mr.
Twotter´s one about sickle cell aneamia are the only ones here that cover everything (almost) fine and in a correct way.
Obviously a typing error though:
chloroquine (trade name Paludrine in UK)
You must have meant Proguanil there instead of chloroquine. Chloroquine is traded as Nivaquine, Resochin etc.
Quite correct: Paludrine alone does NOT help. You MUST combine Paludrine with chloroquine.
Just for the record, some people get bad skin reactions when exposed to sunshine, under Doxycycline medication. Not a good idea in the tropics...
And then, of course, there is always Gin adn Tonic.

You only need about 50 to 80 G&Ts per day to get the appropriate dose of alcohol and quinine.
