I’m 2 weeks and 1 day post op. I am on full liquids for 3 weeks (ends on 4/16/18[emoji4]. I had Smoothie King 3 days ago, and I didn’t have any issues. I got the green tea matcha smoothie w/banana & sweetener alternative ( not sugar). A 20 oz drink was around 182 calories. They have some options (not a lot) where you can have the skinny option. I want to add that I did not drink my drink w/a straw, but with a spoon...& I took my time. Review the options on the skinny menu ( I reviewed online)before you try it. Good luck!
