I may be reading between the lines here, but in answer to your question, "Do you think there are worse conseqences to come?" Yes...if your doctor only wrote your prescription for #10, which was the same number you said you took last night, and also because if that is the case, you have none left to "help with the flights."
Are you saying your bottle is empty?
It is NEVER a good idea to take these other than how they are prescribed. Benzos are a fairly strong class of medication and can really cause damage...you are right; it was a very stupid thing to do. Just don't do it again.
