I don't want to be sober all the time, don't even believe in that concept.
As if taking a substance capable of changing our brainchemistry is something completely artificial which should always be avoided. There is no natural (sober) state, every interaction we have with the environment changes our brainchemistry, incluiding of course the food we eat, the people we speak with, the amount of sleep we get, our stress levels, etc...
And if we focus only on drugs, well... Almost every human being alive today takes some sort of drug, they just use different words (medication, cup of coffee/tea, herbal infusion, cigarette, drink, etc...). By the way, coffee has been illegal in the past and some saw it as a dangerous substance when it was first instroduced.
Who is more sober, an individual experiencing very strong pain or the same individual feeling pain-free after taking a pill? What about a chronic insomniac vs someone who uses sleeping pills?
What I want is to quit my bad habits and work on building good ones instead, so I can hopefully have a better quality of life as I grow older.
