Hi there.....

Looks to me like you've gotten some pretty good suggestions already, but I'd like to add something.

The breakfasts at McD's are likely very high in sodium content. And that will cause water retention. Breakfast can be portable and prepared the night before. How about boiled eggs? Bacon fried chrispy is still delicious cold. I've enjoyed cheese and cold roast beef. If you want a patty - what about a cold hamburger patty made at home?

Hope this helps.
