Ugh! I’m so sorry, that’s so frustrating! I’m dealing with something kinda similar, and I can’t help but feel like they’re just trying to set me up to “fail”. I’ve been on dextroamphetamine XR for over 10 years, and with my current doctor for 4 years. I recently got a phone call saying that I’ll have to provide a urine sample before they authorize any more refills. When I asked why, all they would say is “it’s policy.”
I’m also in a state with legal recreational marijuana and partake intermittently (probably similar amount as you), and have been very honest with my doctor about that. Additionally, I end up skipping doses sometimes when the side effects (jaw clenching/pain) outweigh the benefits, which is another thing that I’ve discussed with my doctor.
I was planning to switch insurance plans (and therefore doctors) in the new year, so this just gave me one more reason to follow through with that plan.
My cat likes to scratch on this weird vinyl/fake leather chair that I have. I’ve tried covering it in tape, and he still scratches it. One day, I realized that whenever he scratches it, he almost immediately turns to look at me, so I started to wonder if he might be doing it for attention. On top of that, as soon as I tell him “no”, he usually walks over to me, looking for attention. It took a lot of patience, but since the chair was already ruined, I decided to try just totally ignoring him whenever he scratched the chair, and giving him positive attention when he scratched on his post. Somehow, it actually worked!
Another suggestion would be to put a scratching post as close as possible to the couch corners as possible, and when you do catch her scratching the couch, very calmly reposition her to the post. Praise her for using the post, completely ignore her for scratching the couch.
I know you mentioned that she has a cat tree nearby, but the geometry of the couch might be giving her a better stretch, she may like the material better, and/or she may be looking for a way to better claim the couch as part of her territory, as a scratching is also an important way that they leave their sent on things.
