The doctors she has been seeing do not seem to focus on that and now we are beyond that and it is constant. The nausea use to begin about 5 am and sometimes go away later in the morning, but most days it would linger until 5 to 6 pm and magically diminish. Somedays she would be free of nausea, but not often. She use to never be nauseous at night, but now since she took the 5 days of antibiotic about 3 wks ago the nausea is 24/7 with no relief unless on 50 mg of Phenergan.
