Risperidone tapering concerns

Hiya guys. I had Risperidone reduced from 3mg to 2.5mg on the 23rd of September, and I've been finding things quite challenging. I've had some suppressed emotions/feelings coming up, which I have been moving through me through dancing, shaking and going for walks. My sleep has been affected too. I've been waking up once or twice a night since my meds got reduced, though I go back to sleep quickly enough. My therapist has suggested that I take lemonbalm and l-theamine. I emailed my community mental health team to see if it would be OK to take this alongside the 2.5mg of Risperidone, and they haven't got back to me. This was a few weeks ago now. Do any of you guys know if it's OK to take it with Risperidone? I've also been toying with the idea of maybe taking a good quality CBD oil, and maybe even seeing if I can get it on the NHS. Do you guys know if I can get it on the NHS? If not, do you know if it would be OK to take alongside Risperidone? Do any of you guys know if there's guidance anywhere on how tapering off Risperidone can affect sleep and how long it takes on average to settle back down again? I have a Zoom session with one of my therapists tomorrow, which I'm feeling very grateful for.
