It seems as though the 1 hr has a pretty high fail rate. I failed and took my 3 hr on Friday, just found out this morning I passed. I have no clue why, but I didn't feel as crummy during the 3 hr as I did for the 1 hour. Maybe it was just random...no idea but hopefully it'll be the same for you! It was just no fun sitting there for 3 hours and getting blood drawn 4x! Good luck!!
This goes for me, too! I threw up immediately after having my blood drawn for the 1 hour and felt horrible. For some reason, the 3 hour test was much easier on my stomach and the drink I was given had a better flavor (lemon lime). Good luck!!!
