Pull your act together!
Hi Economist!
I'm 34 and a philologist... been an alcoholic since my early teens. 6 months might be only the interval you have felt your drinking got madly outta control. This disease creeps stealthily into you long before you might even be prepared to suspect your alcoholism. Do you need a drink in the morning? Do you get shaky if you quit abruptly? You know, classic stuff... So I can't believe this has been happening only in the last 6 months. Nor do I believe that your employer will fire you. Actually I pray that he/she doesn't. You sound like a quality guy, capable of earning one's trust back again even after making a pig's ear outta some business. Focus on not drinking today! Thinking you might get fired tomorrow sounds like a very dangerous trigger.
Best of luck in sobriety, and hopefully with your career!
