So what determines whether someone who is taking lots of drugs will feel bored when they are sober? I once had a friend who I thought was my friend until I realized he intended to take advantage of me and use my money to support his addiction, and when I decided to not be his friend anymore and ditched him he ended up being sober for 25 days and his brother said he actually LIKED BEING SOBER! So why did he not have a "being sober is boring" attitude? I still haven't figured that out.
