Most surgeons release their patients to do "whatever they did prior to their surgery" once healing is complete. Many go to work fairly soon (as early as 2 weeks post-op), but it's recommended to take a longer time to heal before pushing yourself back into the physical demands of work.
Obviously, someone who works at a desk is going to be able to return to work demands more quickly than someone who does physical labor requiring lifting. There are many jobs in between. I returned to teaching after 6 weeks. I'd intended to go back half time at two weeks, but my lungs were still sick with infection, and second grade classrooms are petri dishes. My doctor didn't want me exposed to anything until I'd healed.
Once you've had time to heal, you'll go back to normal eating and drinking. This is a gradual process, and it takes time to progress to that point. I was a beer drinker before my surgery and was worred that the carbonation would create bloating after. I can tell you that after healing, I was able to drink beer again. Soda tends to be more of a problem, and if you're a real addict, you will likely have to modify it a bit--especially in the beginning The only alcoholic beverage that caused me trouble was champagne, as it's carbonated a lot.
Exercise is fine...in the beginning you'll have to take it very easy--walking is recommended until your insides have healed and adjusted. Running can begin after you feel better--it's trial and error. Give runnng a try, but listen to your body. Take it easy with lifting Be sure to consult your surgeon about that.

"Whatever you fight, you strengthen, and what you resist, persists.”
“Worry pretends to be necessary but serves no useful purpose”
“Accept - then act. Whatever the present moment contains, accept it as if you had chosen it. Always work with it, not against it.”
