When I first used this product as directed (take 2 between meals with a carbonated drink up to 3 times a day), it made me feel a little sick so I had to cut this down to just 1, 3 times a day but this was not as effective. Im ok with it now and the sicky feelings have gone. I would recommend trying this product to see if it suits you but as with any product of this type its not a micracle cure however combined with a sensible diet and exercise its been very effective and has supressed my appetite. I will purchase this again :)
