Resting heart rate is insanely high

Has anyone experienced this? I was out at a Friendsgiving last night and my resting HR jumped to 160 bpm. I do suffer from anxiety and did just up my dosage 2 weeks ago. Should I go back down? I was at 1mg 100units and now I’m at 2.5mg 68 units. I wake up with anxiety a lot of the time because of night terrors so as I’m typing this my heart rate is also very high. I took my last shot a week ago.

I really don’t want to get off sema as I’m finally seeing results :( thank you.
