Abdomen injection for the first time left me frozen - had the needle in me but felt absolutely nothing. Panicked thinking I'd damaged some nerves. Hit the lower part, couple inches to the side and below the navel. Weird moment but worth the learning curve.
Yeah, CJC and IPA did help when I was stuck. The water retention shows up mostly in my feet for some reason, which is strange. Lost a ton of weight around my midsection though, which is what I needed.
