For a lot of people, it can be impossible to keep Naproxen Sodium down without food. Personally, I have to eat the equivalent of about two pieces of bread when I take the prescription form. Being in pain and sick is no fun. I tried Aleve, but felt nauseous the whole 12 hours.

For menstral cramps, I take it when the cramps start, and reserve it only for very severe cramps. It does stop the cramps within an hour, but it also makes me feel relaxed / slow-brained, and that makes it hard to work.
