Coffee! But its often cold by the time I get to it. I am really clumsy, but so far - no major disasters!
As for alcohol - I am learning as I get older that wine is just a bad idea for me!! The reason I am writing this at 4.20am our time is because I drank too much wine last night and I just CANT Sleep when I drink alcohol anymore!!! (drink alot maybe twice a year!!!)
However - My husband used to pour me a glass of wine while I was handsewing in the evening - but I never got a round to drinking it!! too engrossed!
I have never drunk wine and then operated the machine though......
