bladder infection
"Please read!!! Presccribed macrobid 100mg for bladder infection. Took the first dose at 5pm after a full meal (on the advise of my Dr who warned slight stomach irritation) around 2 am I woke up vomitting yellow bile which lasted for several hours. I was shaking and sweating and couldn't even keep water down. I'm on my 4th dose and symptoms are subsiding..I  feel like I'm going to vomit, have a headache and am extremely dizzy. Please be careful when taking this its like a flu in pill form!"
