I can’t afford it so I’m not, but in the future, should I?

I had no alcohol at all last night. I have been drinking every night for 6 months with occasionally stopping for a night.

Last night I had weird jolty pain in my chest, I don’t know how to explain it. Just uncomfy jabs.

Not excruciating, just not fun.

So would that mean I shouldn’t stop drinking with no assistance or am I fine to just suddenly stop?
