Does anyone know if you really have to take 2 sachets a day? I use 1 a day, not because I'm trying to spare it, more because I do find it hard to drink. I cant face a second dose or if I do force myself I'll do half a packet well diluted as always. The reason I ask is that the pharamacist gave out to me at my last weigh in for only drinking 1 a day. I'm not starving or anything (bar when I pass the smell of food that is, I know I know its all in the mind), just wondering does anyone have any experience in taking just the one?
