I had a gastric sleeve on April 11th. Since then I had not been able to drink almost anything, in the last few weeks I can manage to drink a little milk, but now about 40 % of the time when I go to rinse my mouth out because I get a bad taste after everything I eat or drink, it makes me gag and throw up. I even tried putting water into a sippy cup with no valve so I just got drips of water and it still hits like 1000 bricks. Anyone else had this problem???
