I've just finished my 3rd week, and I have to confess that Xenadrine is an awesome product, my weight loss now is 11 lbs, and I have another 9 to go. I have consistently excercised, 4 times a week for about 45 mins each session. I haven't changed eating habits of what I've eaten, but most definetly Xenadrine has suppressed my appettite, I didn't realise this would happen. I think the key to success with this product is excercise. You don't have to go crazy with this, just enough to get that little extra out of the supplement...I don't think you have to do as much as I do but try if possible do some. After this comming 4th week I do intend to rest for a week from taking the supplement. I will keep you posted. Good luck in achieving your goals. I know that you'll achieve them with this product, and a positive attitide..my best wishes for your future health and happiness at your chosen weight. If you need any words of encouragement this Scotsman is only too happy to help.
