alifriqui on "Question about daily injections"

Hi there! I am reading a really great book about IVF, called The Couple's Guide to Invitro Fertilization, by Liza Charlesworth. It's really informative, and written in everyday language that is so easy to understand. Anyhow, I'm at the part where she is explaining the daily schedule of a typical cycle. I know many people are nervous about the daily injections (I'm one of them!) and she says the sub-q needles are 1/2 inch long, and IM ones are 1 1/2 inches long. Does that entire length get injected?? All 1 1/2 inches for IM??? I'm less worried about the sub-q's but the IM's are really freaking me out now that I'm reading that. I've had IM shots before, like vaccines or booster shots and things. Obviously I survived it, but I wasn't doing them on my own or having my husband administer it for the first time in his life. Is this as scary as it sounds? Thanks!
