Can I "deactivate" my TD account for a period of time?

I have to buckle down and I need to get rid of all of my internet distractions (yes, I know I'm a spineless jellyfish with no self control or will power ), so I was wondering is there a way to temporarily "deactivate" your account (ala facebook) so that you can't post or anything without reactivating? I may be reaching here, but any assistance is much appreciated
