You must have a Fish Tank. Harvest your fish and go to the refrigerator. This will not cost any money. Get the Shark, Halibut, Eel, and Squid. Go to your stove and make Capriccio. If you do not see that option, eat it raw. You will vomit, but some of your stats will increase. *** You must take a shower after this because of the vomit. Do not do this just before your carpool arrives because you might not have time to take a shower.

If you cannot afford beds for everyone in the house, buy the !!!!Espresso.it.supremo!!!!, which costs 450 Simoleons. Make and drink Espresso until a Sim's Energy meter is full. A Sim will not even need to sleep throughout the game if this is done.
