There are so many things to consider when going off meds ..

It takes time for medications to build up in your system so its going to take time for it to clear out of your system , then... Your brain needs to recovery back to its function before the medications were started.

When I went off my Lithium it literally took about 3 months for my brain to adjust to "pre med" state.

Have you researched the "half life" of your medications? You can also ask your pharmacist for info on the way certain medications will truly leave your system.

Good luck and please reach out for professional help. Stay safe
