At higher levels, it takes far too many drinks to regain full mood. I end up drinking thirty or more bottles of butterfly milk at a time, rather than bothering to create other beverages, since they require too much energy and too many ingredients to be worth the effort. If the effects of beverages were heightened according to player level, they'd be more useful and more fun. (Some of the buffs are useful, regardless of level, but the buffs which give small mood boosts are not useful enough to warrant making the appropriate drinks.)
