I have horrendous pain after a tooth removal that seems to be worsening by the minute 
Possibly a dry socket. I've taken some Codeine and I feel excited. Like I want to jump up and down. It hasn't done much for the pain! But it is a weird feeling
I hate it. I feel like I'm going at 100 miles an hour and going to crash, if that makes sense
I was thinking 'why do I feel excited suddenly' like butterflies in my stomach
Only thing I can recall is the codeine. No exciting events, just a lot of stress at the moment!
I've looked it up and main side effects are drowsiness, nausea (definitely feel a bit sickly), and tiredness
