Jillybean!
What's up girl?!?!?
Are you using up all your reserves? Burning the candle? Under too much stress?
1) plenty of fruits and vegetables, shoot for 5-9 servings a day.
2) Sleep, sleep, sleep. Turn the TV off and hit the sack...
3) take an additional rest day for a few weeks, swap a cardio for a relaxing yoga/pilates/whatever to lighten the load a little
4) get some "you" time every day that is a treat, that makes you feel special, that is not answering telephone, working on the train/bus, grading papers in the bath, eating while doing 6 other things, etc.
I am a vegetarian, take all the rest days I want, shut myself away for "me" time when I need it, do not take vitamins or supplements of any kind, take time to garden and smell the roses and have not had a cold for two years.
I hope some of this works for you and get well soon!
