I drink muscle milk light. It taste good and is low in calories, sugar and fat. It also has a good amount of protien. I take a regular multi vitamin.if it is too big you can always get a pill cutter. I stopped drinking soda two weeks before surgery cold turkey. I had a nasty headache for three days and I wanted soda like there was no tomorrow , but I figured better to go thru withdrawals before surgery than while your body is trying to heal afterwards.
