I am not a sugar-coater, so I'm gonna give it to you straight....this VSG journey is not easy by any means. It's a really big life adjustment, physically and emotionally. I understand your thinking about the pre-op diet and it almost makes sense until you think about what happens after 2 months of doing it and you begin to slowly cheat here and there. Eventually you end up gaining the weight back, and realizing that you need restriction to maintain weight loss.
I too like to be in control and think that I'm strong enough to do things on my own. I'm getting adjusted to my sleeve after having surgery on the 18th of October. I gotta tell you that I had buyer's remorse after I got home from the hospital and realized that I had to succumb to what the sleeve wanted versus what I wanted (which was to eat a massive plate of fried chicken and mac n cheez lol). You HAVE to pay attention to what you eat. You CANT cheat, not even a little bit. You CANT change your mind and have your old stomach put back in. It's a new dawn, a new day and a new stomach; you have to adjust your life accordingly.
My recovery wasn't too uncomfortable, but I think I have a higher tolerance for pain (I've lived thru 3 c-sections). My biggest issue was the emotional part of it, having to come to grips with the fact that I was accustomed to eating food at any time in any amount for no reason at all. I have finally adjusted to my sleeve and hardly have an appetite - in fact I have to remind myself that I need to eat and drink to stay hydrated and get some Protein in my system.
I would say to give yourself at least 2 to 3 weeks to start to feel "normal" again. Some people handle recovery better than others, so i can't really predict how bad you will feel. I can tell you that a positive attitude and staying here on VST to get answers and support really helped me. I realized that nothing good comes easy and that if I really want the sleeve to work for me, I gotta learn how to work it, and that's by following my doc and nutritionists instructions. In addition to that, you gotta learn how to listen to your body because your old stomach is gone. The new stomach has new rules, and if you don't follow them, she'll make you pay! LOL
Overall I have to say, this is the best thing I've ever done for me. I believe in the sleeve!
Good luck and best wishes!
