Yes. Do the best you can. Don't give up before you try. Ember Days are optional (no guilt for failure).
Not only fast but no meat all day as well. The Blessed Mother said, while wearing the Scapular we must say the Rosary every day. Or we can abstain all day on Wednesdays, Friday's and Saturday's. I choose to do both. Say The Rosary every day even when it is hard to pray. and I abstain from meat on those days. It won't kill us to do without meat three days a week.
