Problems with my Prius II :( Help?!!?

Ever since the day my wife bought our Prius, I've enjoyed driving it around and generally saving tons of money on gas and such. It's been a thrill owning the car.

I've always used Premium Unleaded(or whatever the best option is) when filling up, but i decided to save even more money lately. I heard about people filling up with mixes of gasoline and 99% Isopropyl alcohol in order to increase mileage and have a cleaner-burning fuel source. With that information, it only makes sense that having only 99% Isopropyl would mean maximized mileage and eco-friendly emissions.

So with that in mind, I went to the store and stocked up on a enough for a full tank and filled it up with a hose and funnel when i got home. The alcohol was pricey, but I feel it's worth it in the long run when it comes to our planet <3 I poured the Isopropyl into my tank, and I drove around for a couple of miles, i think it was about 8-10 before i noticed something was wrong.

At one point, the car started sputtering, and i thought i smelled something burning. It's probably just the heater, though. The car would sputter and die out, and it would take a while to start back up. This is my wife's car, so i don't want to tell her something happened to it. I left it on the side of the road and took a taxi home. I told her i had taken left it at a friend's house because he wanted to try out the prius for a few days.

My buddy told me that sugar helps break down alcohol. I put a few tea spoons in my gas tank, but that hasn't helped, so i put some in the oil as well because i thought that it might help out. There was no change

I don't want to have to take it in for repairs because she'd probably get mad and divorce me we've been really rocky lately. Is this problem because of the prius itself, and the fact that it's a hybrid and not like other cars, or is it a different matter? What's wrong with the Prius, and what can i do to fix it?

Help?!?!? i don't want to lose my wife and prius, the car is the only place i can go where she doesn't hit me when i do bad things
