These time frames are just guidelines, not set in stone anywhere that I know of. I wouldn't stake my or your recovery on the time frames though, but used to give a general idea of what to expect in recovery and when it would normally happen, but you should prepare yourself to deal with it or at least know about it before it happens. I have known others that have been stuck in the honeymoon stage aka "goodboy phase" then hit the wall anywhere from 9 months to 1 year later... Hope this helps, and with that I'll pass...
