The fluid intake had me worried as well...I was able to drink quite a bit as soon as 3 days post op and still have no problem drinking (not guzzling, but more than enough to satisfy). My doctor said some people could tolerate fluids well, others had to sip, sip, sip (Thank God I'm able to drink okay! Love the outdoors, staying hydrated was a major pre op concern for me.) I was sleeved May 8th and finally able to add flaky fish today...we baked some redfish filets. Tolerated it fine, but I made the mistake of eating two pieces (probably no more than 8 oz. total)...really uncomfortable feeling for an hour or so afterward! As tigerbelle said, you really should consult with your nutritionist. Will keep you in our prayers.
