Seems like as you suggest she has recognised a previous alcohol dependency has come back . I wonder if she has been truthful with the medical experts about her drinking. I’m sure she mentioned in the last 6 months her lethargy had been diagnosed in some part to sleep apnea for example and was now using a cpap. If she is drinking heavily &/or suffering from hangovers most days then I bloody hope she is not driving the kids to school/child minders in that condition . You sincerely hope that she is not just over stating things and using this as this year’s story .
