It's funny, I recently quit alcohol and had a family member tell me numerous times how the friends she knew who quite alcohol were now fundamentally 'boring'. She really wanted to get this message across to me. Now after reflecting on your discussion today, I believe it was classic projection and her fears around being boring without the booze. Unfortunately her comments had a powerful impact on me and I ended up picking up drinking again, (but since then I have quit again)! I realise most definitely, it is 100% the drinking that drains you of all your creative and vibrant energy thus slowly rendering you boring over time.
