Injections vs. Sublingual Drops

I've decided to do injections rather than sublingual drops. I'm not excited about shots, but it's really a time factor. Sublingual regimen requires two doses per day, holding the drops under the tongue for 10-15 minutes. That's a huge amount of time that I can't afford. I've watched quite a few YouTube videos on how to inject, and it seems easy enough. I don't have a needle phobia, so that's that.
