I'm also getting ready for my sleeve surgery on April 22. Start my diet tomorrow super nervous too. I think it's normal to feel this way. I'm focusing on the here and now because the next 3 weeks on 900 calorie daily is going to be my current struggle but it's preparing me for my new way of eating. Looking forward to loosing my weight and feeling better. I have hip & lower back chronic pain. I weigh 247lbs, height 5'3" BMI 42.5 Sent from my Lenovo TB-X606F using BariatricPal mobile app
