Although just skipping a pill may not be enough, Xenical can hang around in your system for hours or even days so you may still get in to trouble with a fatty meal.
If I'm going out I don't normally take that pill and possibly the pill for lunch either. I know it sticks around in your body but if I go over it means the "punishment" isn't quite as bad
I have jacket potatos when i go out. I dont eat them at home so when i do go out its not like im punishing myself eating the samething again. Healthy low in fat and 99% of all food places will sell them.
