That’s a wild question, cause for me and most of the people I know, a fantasy version of myself with double my income would mean not worrying about groceries, maybe a short trip out of the country once a year, being able to pay off debts, and affording some medical procedures that we’ve been putting off. Maybe saving some money so my kid isn’t homeless in a few decades. Not some life of leisure.
To answer your question, though, it would be categorically worse.
Sweetened, doesn’t particularly matter with what. Though I think my favorite has been a honey/citron/ginger tea from Costco. No caffeine, but the flavor was immaculate.
