Such a bummer...but...you KNOW what you can achieve. You CAN achieve it again. I am climbing back up after some success and then falling, as well. It's discouraging to start over. But, look at it this way...you have 155 clean days...and only one or two days of slipping. The good WAAAAY outnumbers the bad. So...you've not failed. You've just slipped. Get up right away. Fight through those first day
