Can't sleep

2:22am and i just can't sleep.  my mind is giing a million different places tonight.  I usually take 2mg of klonopin, Ambien, benadryl to go to sleep...im trying to cut back on my klonopin and ambien but when i do i crave it and get sick.  i know i'm dependent...i just don't know if its a bad thing because klonopin works so well for me.  it has all helped me to get through school.Thing is...its not prescribed to me...my script ran out and im taking my husbands and tge ambien i get from my mom.  i keep having to increase the dosage on both.  It dawned on me that the klonopin may be masking or taking down my mania.  i cant imagune not taking these drugs.  The times I've run out of klonopin I drink, or take hydrocodone or whatever I can find.  I don't take alot of any of it but I've always had to take something since 2006.  Not sure what to think or do,
