I have been taking 8mg 2x's a day of Buprenorphine for 3 months now with no side effects other than trouble sleeping. I'm already taking clonazepam .5 mg 2 x's a day for anxiety. But now, 3 months in to the Buprenorphine I've started feeling like I'm almost having a panic attack after every dose. My heart feels like it's about to explode and my anxiety level goes through the roof. Is it possible for it to give me new side effects now?
