If I ask God for Him to cure my addiction of ADD medications today, then the addiction should disappear right?

First of all how this all started was because I was struggling all my life with ADHD in school been names called like stupid, retarded, handicapped, or just f-cked in the head and I HATE having ADHD so much and want it to go away by God! And then I am now addicted and have abused every one of the ADHD medications and my parents have to hide them and they raise they voices at all everytime I find them and do abuse them. So, if I get down on my knees, and beg again and again like I always did for God to heal my ADHD and my addiction of all the medications tonight, then the addiction should go away, right? I'm hoping so sense He's all powerful!!
