I went back to work after 3 weeks, and had a hypoglycemic episode on the bus on the way to work. Totally my fault - I thought I could wait to eat until I got to work. Lesson learned - eat first thing in the morning! I've been fine ever since. I started hitting the gym again at 3 weeks, taking it easy on my upper body and core. Tomorrow I start working out full force. I haven't been tired or depressed since surgery.
Obviously not everybody can say their recovery was as good as mine. Everybody's different. My advice is start working out now; I credit my quick recovery to a regular workout regimen for the past 2 years. I work for surgeons, and that is always their advice. Do right by your body now. Also, don't be too "strong" for pain medication. They give it to you so that you can feel comfortable enough to live your life without the pain in the foreground. I took my meds regularly and was off them after 1.5 weeks. Haven't taken a pill since.
Most importantly, be positive. There's a good possibility that your recovery is gonna suck for at least a hot minute, but it will get better. Manage your expectations. I truly feel that this has been a gift for me, and I'm so happy to have done this now than to waste any more of my precious life worrying about my diet. This surgery has given me everything I need to move on and enjoy the things in my life that don't involve food!
So there's that,
