I guess the title says it all. It is very easy to get so involved with the foods, that the importance of rest and sleep is lost. Sleep gives our bodies a chance to repair and recover as do rest. When I had symptoms, I noticed that they got worse as I pushed on over what I should have and then if I rested, the symptoms would subside. Actually, it got so bad, because I was stubborn and wanted to keep going no matter how my body was doing, that my body would stop functioning (multi-system failure) and forced me to rest or sleep. I learned the hard way, not to push for though you may get more done in the short run, you slow your recovery down in the long run. So, I forced myself to rest or nap every afternoon.
Now that I am recovered, I don't nap or rest during the day. But I do try to keep in mind the lessons of MS, be kind to your body, don't push it too hard.
Again, good luck to all of you on your healing path.
