Finding a happy balance between relaxation and activities is helpful. Frequently, short naps between activities or outings prevent overwhelming fatigue at the end of the day. Don't plan too many activities for one day, instead space them out over a week. Separate the activities requiring a lot of energy with less strenuous ones. Allow yourself time to regroup while still keeping busy.
Nausea sometimes turns mealtime into a dreaded activity.
Medication may help fight that feeling. A well-balanced diet is important to maintaining a healthy body. Try eating frequent, small snacks or meals instead of traditional, larger meals. Plan meals at times when the nausea is the least troublesome. Be careful not to take vitamins or nutritional supplements without discussing it with your doctor first.
