alcohol recommendations for my purpose

hey guys, i’m not particularly experienced in this regard i.e., finding a drink for a purpose, on which some of you may have subjective opinions and that brings me here. my purpose is to clear the fuzz in the head before sleeping.

picture this: drink a little and go for a walk to feel the effect for some time just before sleeping.

also i wanna keep it for pretty long time. like 4 months (without any sort of refrigeration). would appreciate pretty general recommendations owing to the potential lack of availability of very specific drinks. but if u do have specific recommendations, please drop it, may be i can get it.

and yeah, cost efficient too if possible. again, outside that is welcome too.

the main objective of this post is to collect some info in this regard.

thanks.
