GEAH,
this happened to me with regards to writing, too.
i found out there's something called state-dependant learning/memory, which is defined as
Learning associated with a specific state of sleep or wakefulness or with a chemically altered state, such that the learned information cannot be recalled or used unless the subject is restored to the state that existed when learning first occurred.
i figured this writing thing was a similar situation for me; i'dbasically only ever done it while drinking, and nothing "flowed" without that.
do you have to settle?
no. you need to change
the perspective.
and do in spite of discomfort til you find what's of use and enjoyment.
