Hi Summer, and welcome.
I relate to the hiding and replacing - I did that many, many times. Things that can help the mind in sobriety are support (via whatever you choose - some people use only this board, others supplement with AA, some use SMART, some use AVRT, counseling, church - the list is long). Things that help my body/brain are regular, strenuous exercise and boosting nutrition as much as I can - unrefined foods, vegetables, fruits, and vitamin supplements.
You're not alone - I'm glad you found SR, the support here is invaluable.
