A big congratulations on your days, FIM! That's just fantastic. It does feel great, yes?
Do whatever it takes for your get together and don't pick up. You can do it, and you'll feel the better for it. I've even been with a large group that toasted champagne. I tipped the glass and then set it down without touching a drop.
Just have a glass with something other than alcohol and you'll be fine.
Good going, and looking forward to hearing more.
