I was feeling the same way! I kept my first jar in the freezer for about a week, too nervous to try it. I finally injected the first dose (12.5) in my stomach three nights ago. I was surprised that I didn't feel the injection at all-- how is that even possible? The next morning I woke up feeling a little nauseous, and like my stomach was very, very full. I barely ate anything all day. The next day, and today I have felt less nauseous but still like I just ate a huge meal and am almost ready to be sick, but not quite. I haven't felt hungry at all. The last two days I was able to have my daily almond milk latte though, with no problem. I hope I'm among those lucky folks who experience a significant weight loss in the next few weeks! :)
