Panic

OK..I was rusty on panic.  I started taking antibiotics today in preparation for a root canal on tuesday.  It's been years since I had to take anything like that.  The first two doses during the day I ate with it and was mostly ok.  I had some small discomfort while we were out shopping when it felt like my teeth were getting numb.  I ignored it and it passed.  Steve went to a concert in the bay area so I am home alone tonight.  after I ate dinner and took the next dose I started to feel weird. I have a weird taste in my mouth and smell in my nose.  My stomach was burning so I took an acid controller. I got very cold even with two sweatshirts on so i decided to go take a hot shower and crawl in bed.  In the shower I started to feel dizzy and thought I might pass out.  I'm not even sure if I got all the conditioner out of my hair.  I thought about calling the advice nurse. Then I started worrying.  Did I suddenly develop an allergy to antibiotics?  Is it bad to mix it with the acid controller?  After I got out of the shower I calmed down a bit, let the dog out.  It must just be a panic attack right?  Going to just lay down and try to sleep it off.  Guess I will find out what it's like in the morning.  Crap..haven't been like this in a very long time.
