It's been about an hour since I took my second dose of doxycycline and I seem to be fine, occasional nausea flareup notwithstanding. This time I ate half a peanut butter sandwich beforehand, nibbled the other half afterwards, and have been sipping ginger ale since I took it. I'm not quite in the clear yet, but I think I'll actually be able to make it through the next 13 doses (maybe 12, depending on how they're working, but I lost the first dose of 14 this morning, so 13 to go?)
