I have gotten used to exercising once a day for at least half an hour, but today I didn't do it due to being sick. I felt guilty not being able to walk today :-/. Not walking today made me eat a little better. I ate little and rested, too. I feel much better now and hopefully, I would be able to walk/exercise again tomorrow. Sad to say, that I even cancelled/rescheduled my lab work this morning to next week. The headache caused by my PMS and colds made me feel worst this morning. Thank goodness, after I took a nap this afternoon, I felt much better now. I learned today that pushing yourself into doing something you normally do even for the health sake is not good for the health. Taking a break and having a restful sleep instead is better.
