How to count alternating measures of 3/4 and 7/8

The part in question can be heard here from the song Megalodon by Mastodon.

I have a fair grasp on how to play this, but I’m still trying to fully conceptualize it. My question is, as you lose an eighth note when switching to 7/8 it flips your downbeat on the next 3/4. If you’re counting steady eighth notes now your “1” is on an “and.”

Is there a different way to count this or approach it to help keep a steady beat? It’s even trickier when this same part is double picked.
