I've been put on the antibiotic Macrodantin (nitrofurantoin) cause I keep getting uti's and other antibiotics haven't helped. I started them last saturday and I've been fine, on wednesday I had trouble going to the toilet, then yesterday I woke up with d* and very bad n*. I keep getting waves of dizziness so bad I need to lay down aswell. I know n* and d* can be side effects but I was fine when I first started taking the pills, so I don't know what it is but I feel really bad. Has anyone else been on these antibiotcs and felt like this? The pills are helping but are making me feel sooo bad at the same time!
