My Dr has put me on 8 movicol a day 7 in morning with half hour gap, then one at night? I feel so physically drained what are the best things to eat?

Need more info! Why are you taking it? Movicol can cause diarrhea in so great an amount that there is significant water loss and you can become dehydrated or electrolyte imbalances can occur. Call your doc and ask what you should do.
