WLS in College
Most doctors won't clear you for a return to work for at minimum 2 weeks from surgery. I know I went back two weeks to the day from the date of my lap RNY surgery and was dying. Even though I felt ok at home resting on the couch or on a comfy chair, just the strain of sitting at a desk and walking to and from conference rooms for meetings I was in crazy pain. I wound up working half days and taking that Friday off to work from home. No one at my company knew about my surgery, so I was adamant about keeping it to a 2 week recovery so I could pass off my absence as a "vacation" but let me tell you, I really could have used a third week off. To the people who go back to work after only a few days, I just can't imagine how you'd do it. I didn't have drains or anything like that at home, and I had only the five tiny lap incisions but man did the one through the muscle hurt for a good month. Not to mention, you're just wiped out energy wise. It takes time to regain your overall strength from the whole surgery, especially when you're taking in literally no calories in the beginning. I was still on a clear liquid diet for 10 days after my surgery. Then on full liquids for another 2 weeks before soft foods were allowed. That isn't much nutrition at all so it's hard to have any energy in the beginning.
My advice to you is plan for a two week period of pure recovery afterwards, and keep a third week as a buffer. Everyone is so different, and even the process of the surgery for everyone is so different. It's really impossible to compare your recovery to anyone else's. As far as what you'll be able to do when you first get back depends on what you need to do in your day to day world. Does a return to school mean big treks all over campus to get to your classes? Or is it a matter of parking in the parking lot and walking to a classroom? You see what I'm getting at? If it were me, I'd definitely plan it for over an extended vacation i.e. xmas break or summer hiatus.
With that being said, it's the best decision in the world. It's amazing how you regret it in the early days because of the pain, but as soon as the pain passes and the weight starts dropping like crazy your whole perspective changes and you realize how amazing this opportunity is. :-) I wish you good luck with your pre-op process. We'll see you soon on the losers bench no doubt!!! :-)
