Droopy leaves can come from a variety of sources - overwatering (the state of being constantly wet), underwatering (too dry too much of the time) or a nitrogen toxicity... from what you're describing, you're underwatering, NOT overwatering... At this point, you should be giving enough water so that there is some runoff... let the runoff stay in the saucer/tray for a couple of minutes to see if the soil will soak it back up - if it does, give it more water and repeat... repeat until no more water is soaked back up and then throw away the water in the saucer/tray... When you think she needs something more, lift up the pot - you'll know if there's any water left... if it's super lightweight, give her a good drink with some runoff... if you can tell there's still moisture in the pot, don't give her anything...
Good luck..
