The methylphenidate and amphetty days were quite the days. I abused Concerta (along with Dexamphetamine and Ritalin) and found a way to remove the 12-hr ER wax seal by diluting it in water and would parachute it or even plug it and it'd hit me like a wrecking ball. One of the fewer reasons why Concerta is concealed with a inert to not make it fast releasing is so us abusers find it harder to abuse. Removing the 12-hr ER wax seal is dangerous though. Lots of fun, until the comedown hit me after a multiple-day drug binge and I wished I had a gun to blow my brains out.

My pharmaceutical speed days came to an end once my boyfriend didn't have them prescribed for him anymore and I woke up to myself and realized spending $28 every 9-12 hours along with stealing from relatives and friends to get a "quick fix" would either lead me in a terribly bad situation such as OD or somewhere even worse. The withdrawals sucked crap. My withdrawals lasted 1.5-2 weeks and it can manifest in extreme fatigue, agitation, nervousness and the worst of all, severe cravings for any type of upper.

Up to you to get help and to fix yourself asap, especially that you're probably a beautiful and bright 18 year old who didn't have the best kick-start. With alcohol, I can't provide any advice there. I get *****-faced occasionally and don't struggle with any particular alcoholic dependency.
