Ok, so i started having signs of a bladder infection about a week ago. i was put on a medication for 3 days that ended up not working. so my doc switched me to macrobid. i have been taking that for 4 days now, and my bladder infection symptoms have reduced dramatically, however I am now experiencing extreme nausea. I feel like i am going to vomit all day long, and multiple times during the day i find myself gagging or dry heaving over the toiler. i have not actually vomited though. this is horirble and i still have a couple days of the macrobid left to take. anyone ever experience this before??
