I feel like I'm on a downward spiral...
I like to have something meaty and chewy for my protein. I buy the tuna steaks and cook them in 1Tbs of olive oil with a little cajun spice seasoning. The texture is similar to a beef steak but is high protein, low carb, low calorie, Small bites, chew thoroughly to the consistency of say, tuna in a can. No water 1/2 before eating, no water while eating, and no water 1/2 hour eating. It really fills you up and gives you that full tummy feeling for longer. The water schedule is important because if you have water in your stomach it will flush the protein out and the feeling of satiety or fullness will not last as long as it should.
I picked up a book to read on my Kindle "Successful Weight Loss with the Gastric Sleeve" by Guillermo Alvarez and it outlines step by step what you need to do and why it's important that you do it a certain way.
