I think eflyer is thinking of Arinate. Chinese stuff in it but made in Belgium. If you weigh more than 80 kg you will need two packs. They dont tell you that on the package, you only find out after reading the directions for use.
Yeah two days on that and you should be fine. The first time you have it is bad though.
OBSERVATION: I have not had it since I switched to doudle (triple or mor later in the night) Gin and tonic. Hmmmmm quinine.
