My partner and I both take the Cloroquine, as we travel for a couple weeks at a time to our home on Roatan, not for months, where taking it for so long is ill advised, tough on your liver or kidney (I get those confused, but it's toxic on one for a long time). There is malaria on Roatan, as we have several friends who have had it. Although it's serious and should be treated, I have heard it does not have the same strength of the African malaria, which is more dangerous. I have never had side effects, and take it at night before bed. My partner has, a bit of dizziness, which is remedied by 1/2 of a Dramamine pill. So, bring some Dramamine. Remember, you start taking it before you leave. This is an anti-malaria pill, not a dengue pill, as there is no pill to deter dengue, as far as I know, just the DEET, which you take to deter the mosquitoes. I have heard that mosquitoes don't like the taste of your blood with vitamin B1 in your system so you can start taking that now. Others put on Avon Skin so Soft, and avoid scented skin applications (perfumed). Yet others wear long sleeves, and are particularly aware the mosquitoes are out when the sun starts going down, and wind is low, and apply extra DEET at that time. You can Google "how to avoid mosquito bites malaria" and find other ideas that might work.
