I did what you are considering for the reasons you mention. I sorely miss the freedom of being self-employed. My employer is extremely flexible, but nevertheless, I almost never have time for my personal projects. I'm far less efficient when I'm a FTE because the expectation is that I will bill hours, not work efficiently. I'm strongly considering a move back to self-employment, warts and all. If not that, then maybe a position with a small company.
