While it's of little comfort ghm...the only though I can offer is "welcome to the club". I am the king of backsliding...especially when "winging it". In fact if you read my sitch thread, you'd think I have specifically tried to do the opposite of the majority of the DB-ing advice I've received.
Pick yourself up, dust yourself off, and get back on the DB horse so to speak. Sometimes even the last straw isnt the last straw.
