I started Alli recently and have had absolutely NO treatment effects. I am very strict with the diet, low fat, I write everything down, fat grams, calories, etc... Exercise 6 days a week. I think if you do the eating properly you will not get the treatment effects. YOu can do it. Get a spiral notebook and plan out your meals ahead of time. Write it all down. I find that I will not cheat because I do not want treatment effects. That is incentive enough not to stray from the strict eating. Good luck... You can do it!!!!!
