You know what? I was afraid to. Afraid of treatment effects, afraid of the lifestyle change, and afraid of failing again. So I had the pills for a while before I took them, and like you, had lost my packaging by the time I actually started.
Why not start the lowfat diet for a week, first? That minimizes any treatment effects from the Alli. Seriously, I"ve only had one minor issue, and that was caused by me, eating badly. But ya' know, sometimes you have to give in to a slice of cheesecake so you don't eat the whole thing later! Unfortunately, the meal before it had been at the upper limit of my fat intake, so the cheesecake shoved me over the edge.
When you do start the Alli, maybe do it on a Friday. That way you're system can adjust to it over the weekend. The first couple of days I felt a bit rumbly in my tumbly, as Pooh says, and kind of gassy. Since then, no problems save for the one I made for myself. :)
You can do this. Just want it enough to plan for it and read the package inserts before you begin.
Good luck!
