I purchased a bottle of magnesium citrate, hoping it will help with migraines and anxiety. The bottle says to take 2 softgels with a meal, but they're huge and I'm not very good at swallowing pills to start with.

Does the dose need to be at the same time for benefit, or can it be taken at different points in the day?

As a follow-on, does anyone have experience with taking magnesium for these reasons, and, if so, what dose did you find most effective?
