About to start a four hour commute

I got a promotion within my company that offers a total comp package of 203,000 per year(about a 50 percent increase), and is a massive opportunity. However, it's about an hour and forty to two hours trip each way (roughly 180 miles round trip), 5 days a week. I took it because I know it will be very good in the long run, but I am also literally bugging out. Anyone have any advice? Was this really dumb?
