Type 2 who's been on Byetta / Bydureon since 2007. I can tell you the Bydureon injection _sucks_. Hurts like getting blood drawn every week, plus 5-10 minutes of tapping and sloshing to get the powder into suspension. Annoying the point that I've thought about going back to the 2x daily Byetta pen, but I do get significantly better control with the weekly, and I do a lot of business travel and dealing with the pen, avoiding heat (I'm sometimes in tropical countries) and needing to shoot myself up at specific times is a hassle. But shooting up with sticky syrup through a 23 gauge needle, not to mention being covered with nodules, also sucks.
On delivery, I'd imagine a heck of a lot of Bydureon users would jump for something better -- and "better" is a low bar.
On the other hand, projectile vomiting does not make for a good business meeting....
Was actually going to get a Trulicity scrip at my endo appt this month, but what I'm reading here and elsewhere about much worse GI side effects than exenatide or Victoza has given me pause. Will have to do more research on this. Crap, I was really hopeful.
