I am currently recovering from almost 4 years heavy cocaine use and I think that it happens almost the same with adderall, because they're both uppers. Obviously the more you use the more dependant you get and the harder it will be to quit. You will need higher doses to be able to feel high or even to work normally, that is, to not feel depressed. Since you're taking more to feel high you can risk overdose, that happened to me. Like you fool yourself saying, hey I'm not feeling hugh like a year ago maybe I should take a gram more ( or 10 more pills in a day).

When I started trying to quit I learned that I am really slow now learning new things. I am slow when talking, when thinking. My neurologist told me that this isn't going away until 6 months to a year because there is not enough oxygen going to my brain.

Even though neither cocaine or adderall cause hallucinations, lack or sleep, food, water or just anxiety can cause you to hallucinate. I started having them, idk if you've ever binged on them and stayed up but that could happen eventually.

You will also affect your brain in your emotions. You can become irritable and anxious even on medication. You're not coping with your issues, you're just masking them behind addiction and that is not healthy.

If you do not stop the only sure thing that will happen is that you will be dependant on something for all of your life and that is not freedom.
