Make energy drinks useful.

[HEALIX1]

Right now, spending $15 on 10 energy effectively makes energy drinks comically useless. You can get more energy for less time by napping! How? You make 30 dollars every third day. Or 50 dollars every half day. Add resting to that to recover happiness and energy, plus the food bill. And getting that $15 is suddenly rather expensive already as far as time goes.

I never touched an energy drink until the late game, when I was making the kind of money that let you never think of anything but training. And even then I had to guzzle down lethal amounts just to get a meaningful effect.

Bringing the energy regain closer to 25 would make them viable, still expensive, but actually worth it. It will also have the bonus of making a home gym actually worth the effort. Because instead of having to choke down viciously priced energy bars, you can stay at home, burn out on a multi-day regime, and then guzzle down a few red-bulls and steak to get right back to it.

That, or maybe have that weird herbal tea thing be re-stockable. unless it already is. In which case I don't see why you'd ever go for energy drinks at all right now.
