I guess that's not always realistic? And, more importantly, I'm not sure I like the idea of taking a 'fear-based approach' to solving this ("if I lapse for even a week during a vacation, I'll never be able to get back on track"), even though I understand the logic. Somehow that strikes me as an uncomfortable way to live.
You're overthinking with hypotheticals that aren't relevant.
It isn't lapsing for a week if you were in a rut in the lead up.
Staying in that rut isn't a healthy way to live either. The alternative is to get out of the rut. Blaming fear as a roadblock is a separate issue, entirely.
