when i worked in a hospital vodka used to be the fav drink of the patients as although it does have a smell it's not as strong as other drinks and you need to be up close to smell it on them
LOL, that's what I sneaked in for my mum when she was in hospital. She always has a little nightcap and didn't much fancy the idea of not having one for the 5 days she was in there, so we opted for vodka mixed with dandelion and burdock to disguise the smell. It worked and tasted bloody lovely too!
