Have you let yourself go since having children?

Since you have had children are you running around in sweats most of the time .. you know the mom that doesn't do her hair but once every 3 days and wears comfortable clothing instead of trying to look good for your husband? Then wonder where has your marriage gone? Why aren't we having sex? Or your so tired all the time you just don't have sex anymore? I was reading an article and it was explaining that something like 80% of us moms have and are not noticing we have done it. I at one point was like that but realized that I wouldn't want my husband to be like that. How attractive would that be? Where would I our relationship go if we stopped having sex?

Have you let yourself go? Do you have the support you need to get back to the old hot you? Do you need some support from mom's that have been there? What are your thoughts?
