i took amoxicillin for 3 days because of a tooth infection and on the 3rd day i went in to my dentist to get a root canal. after the root canal i experienced crazy headaches, nausea and vomiting. after 24 hours i started to feel better and of course i stopped taking all meds. after all this i started getting really depressed and started thinking about death due to reading up on tooth infections spreading to the brain and heart. i don't know.. i wish i would've taken care of my teeth better. if i survive then it's a lesson learned.
