Change up her meds.

You figure it was the pills so you work up some new stuff in the lab. A little stimulants to make her more eager and less sleepy, some painkillers to take the edge off, a dash of depressant and muscle relaxer for chemical restraint. Administering the **** to her as the last batch is wearing off is met with quite a bit of argument, but you both know she isn't going to get anywhere before the **** start to kick in.
