The older I get the more I hate the bitterness of alcohol

I used to be able to drink a bottle of beer or two. I didn’t particularly love it but I could handle it. And by “handle it” I’m not talking about drunkenness, I’m talking about the taste of alcohol.

I, with great passion, hate bitter flavors. I can’t even do dark chocolate.

But I still want to drink and have fun with friends and family on occasion.

I used to drink a blue lagoon or margaritas but even those are too bitter for me now.

Any suggestions on cocktails I can make (preferably with available ingredients) that doesn’t have a bitter aftertaste, like at all?
