I found there were times that drinking motivated me. I would whiz through the work day because i knew i'd drink at the end of the day. Or I'd wake up in the mornings, and feel a lack of motivation and nothing to look forward to, so i'd take a drink or two to give me energy and get that rush of excitement for the day. This doesn't work. Like latte said, it gives you hangovers and regret.
We need to find true and meaningful motivation in life. Be it a walk in nature. A yoga class. A book to read. Friends to call or meet. So many fun sober things to do in life.
I do know what you mean - the excitement and rush from the first few drinks is amazing. But those really short moments of excitement and fun only result in regret and hangovers and embarrassment and a loss of money for me!
