Like some of you, I was pretty sure I had a yeast infection. I had all of the symptoms and was on antibiotics, so it made sense. I've never had one, but everything matched up. Being the stubborn woman that I am, instead of going to the doctor I figured I would try to take care of it myself. I chose Monistat 1 being that it was the quickest one. Using it initially was fine. I didn't feel anything. I put a bit of the cream on and went to bed. Maybe 2 hours later woke up to that crazy burning sensation that everyone else is saying they had. I saw this forum (of course after I took it) and panicked. I saw that many took an antihistamine so I did just that. If nothing else it'll help sleep. After probably another hour the pain did subside enough for me to sleep. I woke up with a horrible headache, slight fever, slight nausea, and felt very weak. However, aside from some of the white discharge that many others have had, everything else seemed fine. I have had no issues with using the rest room aside from a very mild burning, which has just about gone away now. I've just been drinking fluids and taking ibuprofen, and today my fever is lower and my headache is less intense. I wish I would have done more research on the product, but lesson learned.
