So I've rolled once before and I took two pills, swallowed one and chewed the other. It was great so I waited a month and took 2 more. Last time I remembered the experience being like 4-5 hours, but this time only 2-3 hours. It really sucked I was having so much fun and then it just stopped. Should I swallow both of them next time and it will last longer or should I take more?
