You seem to have misunderstood my post...I dont NEED energy drinks. I never get the chance to expend any of the miond control energy. The option to do so, just doesnt seem to exist yet in the game (Unless you just have to play deeper into it than I have bothered with yet, because the unbearable grind of doing the ssame thing over and over and over is .... aggravating? to put it mildly.
Are you deliberately trying to play it the wrong way? You don't do the same thing over and over again, because the quest are unique and each interaction shows something new. Granted a few quest have you influence the same person over multiple days, but you get new dialogue and often advancement in regards to sexual stuff.
You can definitely use up all of your energy in a day, I know because I have done it multiple times.
The grind is almost nonexistent. You can cheese blackjack for money if you want, you get nearly enough experience for quest and for the rest you can skip the minigame and still get XP.
I decided to play through the start again, without cheesing money, to play it "proper" and it actually is quite generous with money that way also. One burger minigame per week easily does the trick for the most part.
I truly can't see how you play the same thing over and over, because I certainly didn't.
