Morning sickness Second Trimester

Hey everyone! This is my first pregnancy and I just entered my second trimester, I have had nausea and some vomiting in the first trimester but this past week I have been vomiting daily at least once after waking up... I tend to get better throughout the day... but is the normal? Is it okay? My dr prescribed me some anti nausea meds so I'm starting that this afternoon... we are worried being first time parents and not knowing what to expect... I can't keep anything down until after noon...
