What can I do if my husband flushed my ADHD medication down the toilet?

My husband is very controlling. I take Vyvanse. He's caused huge fights about it. Over 5years my doctor has seen me try time and again to take nothing at all as my husband wants. It doesn't work for me. My husband even called the doctor's office and requested to change my dose 'per my request'. Which I did Not Request. I got a conf. call for my request to change my dose and I was flabbergasted. I had to sign paperwork to remove him from having access to my medical info, etc. This last time my Dr and I discussed taking medicine he advised I keep my medical information to myself. What I'm taking only concerns me, myself, and I. Well, it's been a few months and all has been well. But, today my husband got suspicious of how well I've been keeping up with our home so he searched my bathroom drawers. He found my script and flushed it. I doubt I can get a refill as it's a controlled substance. He thinks he legitimately owns me. I am a stay at home mom what can I do?
