Has anyone else been put on a "z-pack" - basically a 5 day course of antibiotics, where you take 2 stronger pills the first day, and then 1 strong pill for the next 4 days? I had some really swollen glands so I went to the doctor and she said I was developing a sinus and ear infection. I don't react well to antibiotics, so I should have anticipated this, but the strong dosage is making me really sick to my stomach and giving me terrible heart burn. Has anyone else experienced this? I actually think I might call out today because I feel so sick to my stomach. I feel worse today than I did yesterday.
