Stop before it gets out of control and then you will have a major problem on your hands. Take it from EX and BV, I read their stories on how it started and where they went and rose from. It happens to all walks of life and no one is excluded from this disease. I had a serious pain pill addiction for 10 years every single day of my life and I quit and I never thought I could. I dont do NA/AA, it is not for me but to alot of individuduals it is their life saver. There is a site called SmartRecovery that has online meetings you can participate in and worksheets to do on your own. I go there once in awhile. I really get my strength within and here at SR. Just keep posting, we have all either been there or are there. We are here to lean on each other. Hang in there.
Sleep will come in time.
