Look at how relaxed a cat is. He's not thinking about plans for the future. He's not worrying about bad shit that may happen down the road. He's totally in the moment right now.... and all that matters to him is what's happening at this very second. I'll bet you that there isn't a single animal in the world with DP. It's because they know how to stay in the present moment. That's what we need to do.
I like this alot. The best way to deal with DP is one day at a time. I don't think its all about trying to get DP to go away as much as trying to accept things the way they are and improving your life as a whole. DP is not the end of the road and becomes less severe as time goes on. Try to be the best person you can. Strive to be happy and healthy and things typically fall into place. Or, in DP's case, out of place.
It's like that for the majority of people. Since alcohol is a depressant it slows down the nervous system making you less anxious and less concerned with anything DP related. But a hangover will make DP extremely bad, it does for me atleast. It's best just to stay away from any kind of drug or alcohol when going through mental problems. You don't need to be addicted to it for it to be a crutch for your issues.
Definitely socialize. It actually does take alot of effort at first to get past the discomfort DP can cause in social situations but its necessary to push through it. I can't tell you how many times I thought I could stay in an be fine but I never am. Being alone to your thoughts all the time isn't good for anyone really. Just let the people you are close to know about your DP and what you are going through. They will understand.
Dreamer brings up an important point, not everyone experiences anxiety/panic the same. As well as the fact that anxiety and panic are different from each other. Amongst other things I have GAD and PD. GAD affects my daily life. Most of the day I'm in a mild anxiety state. It's pretty strong right as I wake up and lessens as the day goes on, occasionally it will spike up at night. I have anxiety attacks mostly everyday. It's triggered by worrying over the people I really care about and my own future well being. I usually call someone up and just talk to them to have them distract me from the thoughts. If they know I have GAD I normally call the person I'm having the attack over, even though I shouldn't.
PD however, affects me at random. It's very sudden and out of nowhere but I will start to feel a very strong and much more physical kind of anxiety that slowly gets worse. I can feel my heart beating faster, I start sweating, my breathing gets faster and more sporadic, and time starts to slow down. It eventually amounts to a point where I can't control it and I'm in an all out panic mode. I feel like I cant really think or say anything, I just vary between wanting to yell and run around or sit down and wait it out. It's like "the room is on fire and I need to get out or il burn alive" kind of fear. It's just sheer primal fight-or-flight panic. It feels like an hour but they usually only last around 15 minutes. If I have one my anxiety and DP skyrocket for the rest of the day. They are very terrifying but the only real concern is having one in public. It hasn't led to Agoraphobia thankfully, but I am apprehensive to go somewhere If I think I might have an attack.
