I totally sympathy with the OP in this thread.
I use to love drinking, not to fall over drunk, but just to loosen up and be able to be extroverted. In my "real" life I'm a very introverted person - but alcohol gave me the ability to carry on full conversations with strangers about nothing in general, able to talk to women, etc. But always the next day I would feel like a complete jackass.
It got much worse. I can even drink a 6 pack of beer without suffering that psychotic feeling you're talking about. I got to where I only would drink 1 day a week (Saturday), but when I would stop, a few hours later I have would severe anxiety - the pounding heart, thinking something was very wrong and then the adrenaline kicks in and makes it worse.
I later found out that alcohol relaxes everything in your system and when it leaves your system (after you have mentally sobered up) your blood vessels constrict which makes your heart work harder to push the blood through your veins to get oxygen to your brain.
My remedy for this was - well, I'll just drink until I go to sleep and sleep through that stage, so I wouldn't mentally worry about it. Which did help that aspect of it, however the next day, instead of anxiety, I suffered panic. Alcohol makes people that suffer anxiety 10 times worse. Reminds me of Bill Cosby asking someone why they liked to use cocaine, and the person said, "because it enhances my personality" to which Bill replied, "yea, but you're an asshole as it is".
I wish the OP would respond and let us know how she did. For me the feeling does go away, but I am essentially useless for up to 2 days, and suffer the depression for sometimes longer than that after any drinking. I obsess over things I said or typed in a forum, or didn't accomplish. And I feel that psychosis you referred to.
All I can add is, it will go away, but unfortunately for me, I would forget the misery by the following Thursday, and start looking forward to my drinking day again - only to repeat the process.
I still miss a good alcohol buzz, and the feeling of "WHOOOOOOOOW!!!!!", but I do not miss EVERYTHING else associated with it.
The best feeling in the world is setting and accomplishing goals.
Now my greatest fear medication wise is addiction to Xanax.
