i'm having a hard time. i keep dry heaving, pbing and vomitting. today it happened twice... i told the doctor he says it will get better but it so isn't. now of course its only been about 2 weeks since surgery but at the same time i can't help but to worry that this isn't good. i barely eat. i just drink water most of the day, its the only thing i seem to be able to tolerate really well. HELP!
