I am now... hmm... 9 months probably (?) on injections. I was scared as heck from needles and it took me close to 6 months to get used to self injecting and now I am totally okay with it, actually looking forward to my next Tuesday 6pm injection.
The reasons I switched:
liver, health ?
boobs, bigger ?
only once a week vs daily
cycle instead of steady (?)
Of course I have no proof of any of my reasons is true, but I think so, by looking at friends who inject after switching from oral.
