If the hypo triggers a glycogen dump from the liver then long acting carbs are advised to replenish the glycogen. And if the hypo is aggressive, a steep decline, then initial fast acting carbs may only stabilise BG temporarily.
But presumably what is going on here is different - the suppression of normal background glycogen release, due to the alcohol taking priority in the liver, combined with post exercise. Meaning that normal basal is temporarily too high. An ideal case for a reduced TBR for a pump user. Trickier on MDI.
