Ajovy - working for you long term, or no?

Hi! When I first injected Ajovy, I felt angels singing. I could go out in the sun, I felt like I did 20 years ago. Now four months later...not so much. I have read where it works for a couple of months, then that's it. I pay $200 a month for it, so I don't want to keep wasting my money if it's a no go. Any thoughts, experiences, etc.? Any would be helpful! Thank you! -Lisa
