I'm glad you asked, BR.

I also limit coffee, but I have two in the morning and that's it.

I do drink tea but it's so weak it just doesn't count.

I power walk each day, a step down from my running days.

And I follow Andy Murphy's breathing exercises. He writes here. Thy are so good for getting a good night's sleep.

Here's a link to one of his articles.
