11 days to barely feel the first hint of something going on, a month to know it was really doing to do something, and 2 months for the full effect. It did give me a scratchy throat for the first 6 months too, making me think I was going to come down with something, but I never did. Unfortunately, I wasn't one of those instant responders.
The waiting is the hardest part, but you'll get there! Hope it kicks in soon!
Did you do your own shot or did you have help? Are you on the 25 or 50mg shots?
