How much is too much?

How much TIME is to much when it comes to blogging?  I have been thinking about this a lot lately. Am I spending to much time in blogger land?  I really enjoy looking at new blogs, entering giveaways, and writing my own posts.  But at what cost?  Am I ignoring my children and hubby?

Here's the thing though- it's the only thing I do outside of taking care of the kids, homeschooling, laundry, dinner, cleaning- you get the idea!  Right now this is my only "me" time.  I rarely watch T.V. anymore, I haven't scrap booked in ages (about 2 kids ago).  Is it "wrong" to have a "me" time activity?

I used to only blog during nap time and after the kids went to bed.  Then with the move, we are still living with my parents, though that is soon about to change- we are renting a 2 bedroom condo soon (more on that later), my schedule has been a bit more relaxed, so I have a little bit of extra time, and blogging has become addictive. I try to have my reviews and posts done in advance, and I do not post on weekends, but still I wonder am I spending too much time blogging?
My question to you is: How much time do you spend blogging?  Do you have a schedule?  Any ideas, or advice?
