I have MS and I am currently not on any injections. I was previously on Rebif, but because of the expense and the fact that it made me even more fatigued with flu like pain, I discontinued injection treatments about 2 years ago. It had also caused me to start having seizures. So, I'm not a big fan of these medications.
We are just now expecting our first child, so I can't say much about raising a family yet, but being married into a very large Italian family, having two older step-sons, and a restaurant keeps me on my toes. I'm expecting some regression when the baby comes because of the fatigue, but my family has committed to being there to help as much as possible. Having a support team around you is huge.
My best way to stay on top of my MS is lots of rest and stopping when I know I am crashing. My husband helps keep me in check. And I've had to learn to say no to the busy involved in everything lifestyle I once had, admitting that I have limits. As far as exercise...light walking. Overdoing it sends my nerves into hyperactivity.
Hope this helps.
