Hi daniela30,
Thanks for writing and welcome to the alli boards. I am sorry to hear that you're feeling discouraged and frustrated with your weight fluctuations. It is very encouraging, however, to know that you were successful with Alli while taking it and that you can do it again!
I do agree with the other posts that it is extremely important that you set realistic goals for yourself. A one to two pound weight loss is recommended each week, as that indicates you're creating an average of 500 calorie deficit per day, equalling a 3500 caloric deficit per week (there's 3500 calories in 1 pound). This is the safest and most effective method to losing the weight w/o extreme measures. There will be some weeks that you lose more, and others that you may lose a little less, but 5+ pounds per week is a little unrealistic.
Take it day by day, making one good decision at a time and you'll be successful! With the help of alli, a healthy diet and regular exercise you should see positive results.
Best in health,
Kelli
