You have to instruct your sims to drink it.

Tried, they read the instructions (really neat, I must add) but then the maid came by and threw it away (the only other option available was to 'dispose'.)

Could there be a conflict with the (now known to be broken) 'custom food band-aid patch'? Or any other custom food-stuffs? I'd love to use it if possible, just hasn't been thus far.

Is it intended, also to only show up on the Misc. infinity sign? I'd had a hard time finding it to try it. Sorting it to the kitchen Misc. would be more logical, though I'm thinking some hacks on my end may have caused that too...

It is currently set as a misc item, yes.
As for the problem, it could quite possibly be a conflicting object or hack.

Yes, the problem seems to be that hack, and the fact that if you put it on the floor it's automatically made to be empty.

Can it be put on anything else besides a table? I've tried endtables with no luck.

If you do not mind i would like to change the mod so it is available for puchase for baristas in University

where is it?

I love your drink, it works for me, but not the way you intended, I tried to buy your drink , but for some reason, my sims could not interact with the drink once I bought it, I had also downloaded a monster drink from comedy711, it is just juice no special effects, yet when I had the sims get the monster drink from the fridge and drink it, it gave my sims an energy boost, I have no idea how this is happening, not getting any ill effects from it, so far, just wanted to pass along the info , also gave comedy711 the same message.
