Welcome! Im so glad you are here!
I was a secretive closet drinker as well. No one knew how much I was drinking and I put alot of energy into that lifestyle. Sneaking and lying was part of it and I swear that was part of the lifestyle that I needed to break. Being able to be more authentic/genuine alng with being sober has been so nice. Closet drinking takes ALOT of our energy ya know?
So maybe changing up some routines, really think about what some of your patterns were and make changes to that. Like if you did most of your drinking at nights, findng things to fill up and distract that time. I used things like reading here, getting books from the library or from amazon for my kindle, books on recovery, writing ( typing) in a journal, I listed all the negative affects of my drinking etc.
My best wishes to you. Stick around here, lots of loving kind supportive people here to help you on your journey!!
