The Vitamin B1 tabs and eating lots of Marmite has been around for a while, fortunately eating Marmite is a pleasure to me. Couple of tips as said earlier, Boots anti mossi is the best but you need 50% Deet. you can get roll ons which still need spreading, sprays which make the bathroom floor sticky and gets up your nose. I use the sachets which come in boxes of 15 and are simple and effective to apply. Im lucky that I don't attract too many but when I went up the Amazon with JY a few years ago I made every precaution, wrist bands which kept falling off, Mountain Warehouse anti mossi impregnated shirts and to top it all I applied some 100% Deet which I got off the internet but it melted my watch strap so didn't use that any more. in fact I was so hot by the time I got ready I had to have another shower. after that I didn't even apply anything and I was fine. Last little tale, I was away once and there was a lady who was trying the Marmite route but unfortunately she was not aware you are supposed eat and she had rubbed it on her arms and legs, we could all smell the marmite but at least she didn't get bitten
