So SWIM will take some E this sunday and his idea is to disolve his pill in a 500ml water bottle, but SWIM doesn't know how much and how regularly should he drink so the effect could last 3:30-4 hours. SWIM doesn't want the effect to be as strong as possible but to be enough for SWIM to be satisfied. This will be his 8th pill overall and he took one last saturday. SWIM weights 90kg and is 1.85m tall. The pill SWIM has is a green party flock, which has 180-210mg of SWIM's favourite chemical, MDMA.
