I'm 56, 5' 10" and was 375 at my heaviest last august. Went to weight watchers and lost about 60 lbs prior to my surgery on may 13th. I've had no issues at all. 10 days now and soreness almost completely gone, didn't have too much to begin with. I'm having no nausea, no trouble getting my water requirments down, protein, ect. Still on liquids, Start pureed next week. Hope this helps, Good luck ! I'm also walking 2-3 miles a day with no problems !
