5 or 6 before getting laid off. 8 or 9 now and loving every minute of it. I can't tell you how much better I feel. I can take power naps on the couch and often solve the prolem I've been working on all morning, just after waking up. I work the entire day with breaks whenever I want and actually end up working 9 or more hours.
It's also great to work on my startup full time. My office is now the patio table if it's sunny or the back porch if it's raining. It's amazing how hard you'll "work" to not have to go back to "work".
