i recently took Malarone but had to stop as I suffered from stomach cramps, diarrhoea, disturbed sleep and mild hallucinations. I have also noticed now that my nails on both hands and feet have a yellow tige part way up the nail bed - could this potentially be another side effect from taking the drug? i am a 43 year old female, 5 foot 8 inches tall and weigh 59 kilos. I am very active albeit still have some ligering effects from having taken Lariam 18 years ago.
