Cross country move at 30 weeks

Due to some very unexpected issues with my husband and I’s living situation we’ve been left with no choice but to move from Northern California to Northern Virginia. I’m just bordering 30 weeks pregnant and I’m obviously very upset about this move being so last minute. The drive will be about 41 hours and my husband will be driving the whole time thankfully.

My question is, how can I make this drive as comfortable for myself as possible? Any snacks I should bring? Any tips for insanely long drives? We’re stretching the drive out over 5-6 days so we’ll be in the car 8-14 hours a day depending on traffic, the cities we’re near, etc.
