Depends on the circumstances.
I've been known to start drinking at 8am while doing the Xmas dinner. On holiday I have a drink by the pool about 10am. At T in the Park I have cider for breakfast at the crack of dawn. Brunch with the girls at 11am...yeah I'll have a drink. These are good things.
Bad things are...not being able to function in the morning without a drink. Drinking to wipe out bad memories. Drinking to make you feel better. Drinking before you go to work etc.
