ADHD Waivers

I went to meps yesterday, and I got flagged for ADHD (which I was expecting) because a little over one year ago, on January 20th to be specific, I was diagnosed with ADHD because I was having trouble focusing in class when I was still in college. I was prescribed a 30 day round of vyvanse and ended up only taking it for a few days and stopped because I didn’t like how it made me feel, which I know in the long run doesn’t matter because on paper it’s 30 days. The physician said if I went to meps next week instead of Tuesday I wouldn’t need a waiver because it would have broke the one year threshold. Was just wondering approximately how long it would take for the waiver to get passed through, if anyone has a guess. Thanks all, sorry for the long post.
