You're just going to have to wait it out unfortunately.
How did your meds get destroyed? Has this happened before?
If your doctor has reason to believe that you are abusing your medication he will not re-prescribe it to you. Worst case scenario you could be pulled off the meds completely and flagged as a potential controlled substance abuser which will have big adverse effects on your ability to be prescribed other medications in the future as well.
If your meds genuinely got destroyed then you should arrange to meet your physician and tell him exactly what happened. If you don't sound like your making up a BS story and you have no history of 'losing' your meds then generally they will throw you a by-ball and write you up the remaining amount of your script.
ADD meds are serious business and are high risk for abuse so it's understandable why your physician might not want to just willy-nilly write you a new script.
