Morning ItsJustMe89
If you are like most of us (we've all slipped at least once) then you will hate yourself today. DONT !!
Think about what led up to last night. What were you doing that day? who had you been with? Where did you buy the drink? where did you drink? who with?
You can learn from these things and know what to avoid next time. This makes you stronger and means that this time round you are in a better place than you were eleven days ago. Eleven days is a huge achievement which I'm sure you can repeat and beat.
You can do this
