If you are willing, lets try an experiment. The drugs likely change the way you taste but not that you can taste. Soak a 1/4 cup of raisins in 3/4 cup of water overnight. In the morning, drain the soak water into a glass and drink the water. If you can let me know whether it tastes sweet, sour, salty, or bitter, or like nothing to you, I think I can help you from there.
For the time being, you are much better off eating whole foods (the sort which comes from the produce aisle) than packages of stuff.
This, too, shall pass. :-]
If you go the People tab, you can search her by name and can get to her wall to discuss further. Hope I found the right one for you.
