I came here to say exact same thing. I think a 30-40% pay-cut is OK as far as you choose a really more fulfilling job.
But about regrets: There are days that I doubt my choice too. Probably because I never experienced working at big corporations. Maybe I'm OK with them? Maybe I should go experience that for myself? But usually these doubts don't last long. And hopefully your more experience helps you never encounter these doubts! ;)
