Multiple Sclerosis: I'm so tired! Fatigue and MS

I echo her thoughts and perspectives here.  I make myself get up and go about my day.
Give MS an inch and it will take a couple yards.
My motto:  Move or you'll stop moving.
Yet, as she says, if you're in relapse, have an infection, or feel like you're about to relapse, rest.
Rest as much as you need to in order to get up again.  You'll get to know your body.
Be patient with the process of getting to know when to push and when to ease off.
