Nobody is suggesting you be a "non social loser. . . missing a lifetime of memories"
Short term, you are trying to get in the habit of sobriety so that may mean
not doing everything you usually would do if it will trigger your drinking.
It isn't a life sentence by any means
After your sobriety is established, doing normal things with friends and family is
very easy and enjoyable.
You just don't have the burden of addiction hanging over your head.
Trying to control or moderate is usually much much harder than just not starting.
