I am on Xenical too. I also am doing weight watchers points system. I stay on program and still have side effects. I have had good results with both the drug and the program losing 15 pounds total. I have been on Xenical since January and WW since April. I have lost the weight slow but so far I have not went up and down. I'd love to offer support and my experiences with x. Good luck and don't give up!!
