I can relate, and have at times wondered if I took my med when I was supposed to. One thing I have done that helped me, is to buy one of those divided containers that is marked Monday through Sunday.
Simply put you're daily does in each slot, and you will know if you have indeed taken the correct daily dosage. At the end of the day on Sunday, refill it for the next week, and so on.
I'm sorry that you will have to tough it out for the next few days, but please take the steps to see that this does not happen again.
