Did my first injection today! It went much better than I thought. It only took me about a minute to get up the nerve. I am so relieved. I think I'll be ok doing the injections once a week. I noticed that I got a headache about an hour after, and now I'm exhausted. That may be from being revved up about this appt. I Googled it, and it seems headaches can be common for a few weeks. Any early side effects that you can think of??
