Stay away from LARIUM if you can. It gave me tremendous psycho-dreams, with very vivid colors. It's the only time I have ever had an anxiety attack....and that, while flying in a small prop over the Masai Mara and sitting at the exit door.
Many of the people we met in Africa were on larium. Since you start it x number of days before your arrival in the affected area, everyone seemed to be on a different schedule. So, at breakfast each morning, the discussion would eventually turn to "OK....who took their larium yesterday....and what kind of dreams did you have."
One of the tourists was an MD, and she started getting anxiety attacks so badly that when we got back into a city (Nairobi? or Jo'burg) she actually went to see a doc to get some sedatives.
There are many sites and blogs that document the side effects!
