You're in great shape but without projected expenses (you make some general statements that suggest you have a number or could easily develop one) I don't think we can provide concrete assessments. Maybe I missed it in your post, but have you tried FIRECALC? Very good place to start.
I would suggest you ignore anyone who gives you a firm yes or no based on your financial picture. Only you will know when enough is enough ($ vs living), it's not strictly a financial decision IMO. And welcome aboard.
