I was out a full 6 weeks per doctors orders (I had the full Nissen wrap w/a couple complications...almost a 5 hour procedure). I'm just about to hit a year since my surgery, and I'm eating anything and everything I want. No restrictions, no problems, no nothing. It feels great to have had such a successful outcome, despite the difficult recovery. I wouldn't change anything (well, except the complications during surgery).
FMLA is actually a full 12 weeks of protected leave. If it's been over a year since your last leave, you should get the full 12 weeks to recover w/job protection.
Be well and take care!
