HI THERE, I was bypassed August 2011 I was uo and abiut same day. Was not allowed home til 2 days after would have been able to come the next day but live too far away from hospital and had bad win pain. Cam e home 2 nd day after. I do not drive so I don't know about that, however I did go back to works after 2 weeks but I did no heavy lifting at all I did do too much in the 1 st week stretched up to peg out some clothes, spent the rest of the day in bed resting. B12 started I think within 1st 6 months have them every 3 months now without fail. Take your required vitamins daily, if you don't you can leave yourself open to being deficient and bigger medical issues further down the line. Well bowels can be an issue for most I think. I thought I had IBS before the op docs said not but I had the symptoms. Since bypass have periods of constipation and then periods where I can go naturally. After the op constipation can be a big issue for some I found sunsweet prune juice to be a godsend. Keeps you regular, some people suffer diaorhhea. I suffer form bowel colic when its bad its bad. I can go days without an episode yet an attack lasts for few hours and after 5 days I can feel normal again but the 5 days after I feel bruised inside. Apart from that I am fit and well and manage day to day life as I have always done. Good luck with the op hope it all goes to plan xxx
