Yep. I go to the gym 4-5 times a week plus ride 34km on the weekend when the weather permits. My p's take the kids for a night or two almost every school holidays, we're going to a wedding sans kids soon and staying overnight at the place the wedding is at. I just started uni and currently am there every day for two weeks...I love being me and then walking back in the door to see my kids and spend time with them!
I couldn't go a month yet but I'm most certainly not one of those mum's who never needs a break from her kids. I'm a much better mother when I get time for me too and my kids love it as well!
