Welcome! I am Canadian too eh?

You will find great support here.

For the bathroom issue, I take magnesium citrate tablets before bed. Helps with leg cramps, sugar cravings, and bathroom issues. They come in 150 mg tablets, I purchase the big bottle at Costco. I generally take between 300 and 450 mgs (2-3 tablets) depending on how the "go" has been going LOL.

For the headaches, you may need extra salt. The salt thread here. Read it even if headaches aren't an issue. Very informative ( thanks Nancy LC!!!!)
