I gotta admit I've been a pus when it comes to self-injections, I've always had someone else to shoot me and that can really complicate things. Anyway, I bummed some pins from a farmer friend of mine and all he had were 18 gauge 1". Not ideal but beggers can't be choosers.
Anyway, I got drunk last night and gave myself my first shot. (I know that is probably not the smartest way to go about it but oh well.)
This was one of the simplest things I've ever done. Very little pain, etc. I'm embarrased that i've spent so much effort avoiding doing this simple thing.
If you have a fear of injecting yourself, check out some of the educational threads and then just do it. You'll be glad you did.
