Thanks everyone.
I definitely know my triggers and actually find these little slips a learning curve. Yesterday I had been working and planned to walk my dogs but I was in a lot of pain in my legs from a trapped nerve in my back which meant I couldn't get out with the dogs or do anything much, hence I made a conscious decision to drink to ease the pain and boredom. Today I am pleased to say I slept badly, my stomach/liver are painful so hopefully a lesson learnt.
