Tiddly

Tiddly means slightly inebriated is first recorded in Punch magazine 1895 and may derive from an obsolete word tiddle that dates from the 1500s meaning to indulge to excess. The OED maintains, however, that it derives from a mid-19th century noun, tiddly, that means an alcoholic drink but hedges it bets by saying it perhaps derives from rhyming slang, tiddlywink/drink, which is first cited from 1880.
