I had my surgery May 29. You sound exactly like I did the first week. No pain meds needed, walked, protein drinks, chewables, etc. Just don't overdo because this week, I'm feeling more pain and indigestion. I keep forgetting to take tiny sips!
Anyway, feeling tired this week, more so than last. Hopefully, everthing will feel better shortly. Just don't over do it because you feel so good it's not worth it.
