Unfortunately I'm sure we all have them. Let's share and maybe have a laugh or two.
#1 worst: Internal med guy in PHX area when I had been TI for about 2 years. He told me to quit being a slave to my bg meter and take the same amount of R for every meal. My next A1C was 12!!!! He was also more interested in talking about the studies he was doing on Native Americans than what was happening with me.
#2 One doc suggested that I might try one of the oral meds along with my insulin injections

Excuse me??? If I am TI and no longer producing insulin what good would that do?
#3 I was referred to another internal med guy in the PHX area that couldn't speak English- he was from India.
#4 The "doc in a box" that I saw only once to get approval for my pump (no one else in the wilds of southwestern CO would do it) who disappeared in the middle of the night about the time my pump arrived. Thank god for "Pumping Insulin" because I never had any training and taught myself.
OK, your turn
