I think I fall under this category. I am day 4 on D. Sorry have not weighed in as yet will do in 3 days time. My side effects are nothing to what I have read out there. Thirst is the only one - I just drink water. I can hardly eat a thing, its not an ill feeling just a full feeling like I have already eaten. Its wonderful. I would never have believed the human body could feel full on nothing. I do force myself to eat but every time I swallow anything I feel fuller. I woke up at 2am on the first night, at 1.00am the second night and 12am the third night but only to wee and fell right back to sleep - so no insomnia for me, not feeling on a high, no headaches, no extra energy. Just feel like myself beside the thirst and not physically eating. I weigh 70kg, am 156cm tall and am hoping to reach 55kg at the least by the end of the month.
