spoonful of suga'

i must say, i love cough syrup.  how can one little spoonful of something that tastes like vanilla make you feel so, what's the word i am looking for, drunk and happy and warm and fuzzy.  there has to be a word for that in the english language.  why doesn't that word exist???  without it, i don't think the language will be able to continue!!! 

it could be the cough syrup talking.
