Imo, It's okay if the views drop off after the spike, that's normal for any update.
Coming out of hiatus yesterday, I recently shifted to uploading and scheduling a whole chapter (in single page uploads) so everyone reading has that to chew on while I keep my head down and work on the next chapter.
It might help to not think about just the pace of updates but rather finishing the story and then worry about spreading it around to find new readers. The end goal of a finished comic is just as important if not more cause by then readers will at least have the whole story to view and comment on.
Especially if you have time constraints in your life. Sometimes you just gotta accept what's not in your control and work with what is.
