Another round of cheers

[catfish]

Can anyone help with a final few questions I have left? No 8: Don't heavy drinkers go for this? (5,3)
No 14: The doctor joins me for a drink (5)
No 21: Drink available at the cemetery (6)
No 23: Forced Gershwin to have some cake... (7)
No 25: Favourite tipple of a weather forecaster in two minds?(4,3,6)
All answers contain an alcoholic drink.
Thank you
