You don't say what it is you're concerned about. If it's health, well, of course all three are unhealthy, but I suspect you're asking something else, we just can't tell what. More detail?
Hi Susan,
I read somewhere that after you ingest coffee, the coffee stays in
your system for 8 hours. If you have trouble sleeping, try and drink
coffee in the morning. So let's say you drink the coffee with milk and
sugar at 2:00 in the afternoon, the coffee will still be in your system
by 10:00 at night. I'm very sensitive to caffeine, so I try not to have
any coffee after 12:00 pm. Cheers, Eve
