Adderall works (side effects suck) v Ritalin which makes me sleep?!

I hated the side effects of Adderall (IR 30am, 20afternoon... I'm already prone to anxiety, no interest in food, and felt dehydrated no matter how much water or electrolytes I took in - dropped crazy weight, super fast) SO, my DR. switched me to Ritalin (2/20mg AM - 1 20mg afternoon) in hopes that the shorter acting (3-4 hrs) would allow for easier meals in the AM and PM. I also have major problems sleeping, but that's from... always. I take a sleeping pill to help calm my panic and nerve attacks and help me rest.

Anyway, I'm totally frustrated. Adderall helped me realize how easily I can get sucked down the distraction rabbit hole and problem solve to finally complete assignments and projects. NOW Ritalin just makes me want to lay down on the couch and even with a pot of coffee... nap in the middle of the day despite getting eight hours of sleep the night before.

Why? What's the difference? I just don't understand. I seriously hate ADHD.
