Morning christmas symptoms and conditions

Lucky me- I started MACROBID Christmas eve for a UTI. I have never taken it before and felt nausea that night then the next morning (CHRISTMAS!) when I woke up I felt like I had been out drinking the night before. I had the worst hangover-like headache. I was tied all day, no fun on Christmas day with three kids, and then I took my nightly dose and headache got worse and I felt like I was going to vomit for many hours after that. What a crappy Christmas day. And lovely gas all day too. I am going to call the doctor in the morning to see if I can start something else! I will be careful to read from now on the possible side effects on any medications I get and be aware of what is happening to me!
