Don't worry, because it all comes back. No, you won't be high, but it all comes back. When I realized what was happening, I had been prescribed anti-depressants on top of the high dose of adderall... I smoked tons of weed for a while to leave everything else behind, which may have prolonged recovery time.
I recommend that only if real life isn't cutting it, but know that you CAN wait until nighttime. Eventually, weed gets in the way, too, and then you stop smoking that. Edibles could be better. Hash is cheaper for those. It's a better way to look at the world. Whatever you do, don't do THC and amphetamines at the same time; it's a waste of human potential.
So many people have been addicted to speed... If you stop, you get your life back. I hear it takes 2 years with adderall, before you can forget it. I am still waiting, patiently. Use those two years to discover yourself. For weight gain, look up trophology. Take digestive enzymes with every meal. Exercise will help with the recovery process.
Adderall is ridiculously addicting, and the knowledge of that is now part of who you are. It even made me more selfish. You can look at that any way you want. You might not forget how it felt, but the fact that you don't want it means you might be ready to stop. I like myself better off it, but get ready for some bullsh**t depression. I blame the doctors and teachers for their misinformation and laziness. Also, remember not to go back to the same people for benzodiazapines (like xanax or klonopin), or you'll have the same discovery.
But, know that the brain is capable of amazing things. The feelings aren't really the result of any brain damage, per se... The adderall is just forcing connections you would never make on your own. When people do have brain damage, however, the way their brain recovers is not by repairing, but re-wiring. Every day you avoid adderall (and maybe eventually weed) is your VICTORY. Your neurons are forming new connections, and that's how your motivation eventually returns. You don't have brain damage, you have a brain. Feel better yet? That's real. The mood swings are hard, but the way you deal with them is something to take pride in. In time, or no time, you could feel more creative than ever, but, more importantly, you can once again feel like your own person.
