Neither have ever been a huge issue in my life. Sure that year after my Dad died I went off the rails and tried just about everything and took some stupid risks and spent far too much time drunk, but I do not beleive I am any worse off for it now.
I am not much of a drinker, will ocasionally let my hair down and get a wee past sober, generally only in social settings and then also only with the right people.
Drugs no longer appeal on any level. I think I am too old to deal with the day after..lol. I like to be in bed by nine most nights since I get up super early.
I think you should be free to try everything and do exactly as you please as long as you remain mindful and don’t inflict your bullshit on the people around you who deserve better.
