Hey,
Absolutely do not even consider reinstating. You did the right thing by not tapering after 6 doses. If you are struggling after such a short time taking benzos, imagine what could await you if you took them for longer!
But the good news is you've probably done the hard part already, things should just get better and better as the days/weeks go by. In the mean time you may want to look at some supplements, or maybe an antihistamine to help you sleep for a while. I am assuming that you're are not sensitive to these things because you were on such a short time, but some people can react a little to things after a CT so just be aware it could happen. I personally don't have a problem with my sleep but many do, you may want to have a look on the insomnia board, and alternative therapies board.
I'm sure you'll be fine in no time
