Help! Meds stopped working!

Has anyone else had this problem:  Suddenly I am having severe slip-ups even though I am taking Adderall regularly, 2ce a day.  2 days ago lost my keys and metrocard.  Yesterday was a logistical nightmare, all 'ADD moments' leading to me being 45 minutes late meeting someone, and forgetting to bring essetial items...  then I ruined dinner.  this morning I was going to fold the laundry I did before going to bed, only to realize i never put it in the dryer and it was still in the washing machine getting mildewy....  Burned breakfast this morning because i couldn't handle making bacon AND pancakes at the same time.  Totally exhausted and fell asleep for two hours (can anyone else sleep after taking 20 mg of Adderall??)

WHAT'S HAPPENING????

I'm panicking a bit because next week i have to travel with my kids and I have to have my $#!t together!  Am i just getting a higher and higher tolerance for it and it's not working anymore?  will I turn into a speed freak needing more and more of this stuff???  or is it just not working anymore?  Or is it just a bad couple of days??

HELP!
