"started on these at the end march. lost 10lbs in the first three weeks, not a great deal, but i only have 2 1/2 stones to lose. had no appetite in the first week but it has returned a little in 2nd and 3rd week. not that much though and i&#039;m eating much healthier. however,just weighed myself this morning, at the end of my 4th week and i&#039;m gutted to find i&#039;ve only lost 1 lb. although i did have a little bit of chocolate egg and haven&#039;t had the chance to go on my wii fit as i usually do nearly every day. now i&#039;m wondering whether i should stop the tablets for a couple of days to kick start them again. as i have read that others have done this. only thing is i had headaches for first three days when i started them and don&#039;t want a repeat of that."
