Well, while there's no direct way to prove that it's a causation of whatever he might need pills for... odd that this happens when he starts getting closer to her, no?

We kill 'that woman' or at the very least drive her away from Michael with use of force or scare tactics...
Or we try and sabotage Michael's opinion of her, potentially using actually confronting Michael about it.
I don't think the third one will work if this is a temptress doing a honey trap, since if he's in- he's not getting out without force.
