Well my friend, first of all what is your purpose of drinking alcohol? If its just about relaxation then there are plenty of alternatives... coffee and tea are the best.

Now my friend, as far as I know, alcohol were made to intoxicate and party party! So if you would only drink a bottle just to relax, then the alcohol is not serving its purpose to you... but here is the catch, if it serves its purpose and intoxicates you then yes my friend, it is harmful indeed... Bad for you, bad for your loved ones too.
