Lariam has messed up a lot of people....I used it a lot when it first came out, and I also had no problems...but I know people who did....ranging from wild nasty nightmares to full hallucinations in seeing people who weren't there....another in Tanzania with a friend I had booked a hunt for....our tents were bout 20 yards apart and I woke up to him shouting for me ....said a lion was trying to get in his tent....I got my rifle and torch and slowly unzipped my tent and went over to his....as he saw my torch he came out of his tent....I walked around his tent and saw nothing....he told me he had heard bones crunching in the small thicket behind the tents, then he had coughed and the noise stopped. Next he said he heard panting/breathing outside the tent opposite to his bed....he said then the "lion" had pushed its muzzle into the tent wall pushing it in...then it came to his side where the bed was and did the same...he said he was shouting for me during this time but I never heard...so whether he imagined shouting or not I don't know...he said whenever he moved to one side of the tent or the other it followed....I looked around the swept area around the tent and couldn't see any tracks, and no possible damp patches on the tent from the muzzle or mouth....I told him there is nothing....he said I am sharing your tent...he got in the 2nd bed in it and I went to sleep....he then woke me up freaking out saying its back...listen you can hear it breathing and waking around ....I couldn't hear anything...he kept saying there and pointing....I said sorry I can't hear a thing...he got pretty pissed off with me and in the end i got my torch and rifle and stomped off outside as I wanted to get some sleep....I looked around and nothing....Next morning my friend the ph came from where he was sleeping and we had a good look in the thicket...no bones...looked around the tent and in the clear day light no tracks in the swept dirt....after this he hunted in CAR or Cameroon and told me he was having a shower in the the grass thatch walled shower and as he opened his eyes from rinsing off his shampoo he said one of the locals was standing there looking at him...he said he shouted what you doing in here....then blinked his eyes and the "person" vanished....his wife was a child psychiatrist and in one of her medical magazines she saw an article on lariam....it said one of the side effects was people hallucinating ....so she told him and he realised after thinking about it that these 2 incidences were down to him taking lariam....his next hunt his doctor gave him lariam again...his doc when he queried this said if you are rational enough to work out that's what happened its not a problem you taking it....apologies for the long waffle...but he was terrified during the tent episode...he really thought a lion was trying to get in and I couldn't hear him....
