I have noticed that my hiccups seem to be triggered by two things 1 being exhaustion and the other a long relaxing shower. Well surprise I had jut finished my shower when I got this aggressive hiccup attack. Normally the attacks happen while im in the shower covered in soap and are gone as soon as I rush to get out and turn on my camera. So for them to wait till after my shower was completely over was a nice change. These just go on and on so I decide to tell some nursery rhymes to see how badly my hiccups would interrupt them and how man I could finish before the hiccups subsided!
