Anyone using SelfControl on a Mac?
 

Lets you block certain sites, email, etc. for a specific length of time. Even if you delete the program they are still blocked.

I wouldnt need it, but being honest, I'd also be hesitant to trust it.

Trust it as far as that it would give me control back when promised (ie it wouldn't fail) or that while I dont have control, I would need to be certain it, (or someone else remotely) wasn't being given control to do things that I - not having access myself - would not want them to be doing...
