Does applying sugar to the tongue taste buds releave sugar withdrawal symptoms?
Theoretically if you could somehow activate the G-protein-coupled receptors (GPCRs) corresponding to sweet stimuli without absorption of the sugar into the bloodstream than it may be possible to "trick" the brain. (See this review to learn more about how taste signaling works). However, the process of absorbing sugars into the blood stream begins in the mouth (see this question), so testing your idea would be nearly impossible.
