my 16 year old had knee surgery and at first she was taking 6-8 vicodin 500mg a day now she has backed it off to about 2-4 a day she was in the shower today and kept complaining how hot she was and it wasn't hot in there at all next thing i know she said she was dizzy i reached in the shower to help hold her up and she blacked out and went limp for a couple minutes i then got her out of shower and all she wanted to do is lay on the cool bathroom floor
