I am 11 days post op and I was thinking of trying a sugar free smoothie at two weeks. Did anyone try these at that time?

I made some protein shakes at home with fruit in them ( banana or peach, nothing with seeds - my doc said no seeded fruits for 6 weeks to make sure they didn't get stuck in the healing tissue in my stomach), soy milk, ice and protein powder. Fruit has a lot of sugar and I couldn't drink much of it. At a month out I still sometimes can't handle fruits due to the sugar content.
