Forgetfulness and sleeplessness.

Hi, I am 34 year old female with a baby of 11 months. While I have good academic and professional record, since many years I have been experiencing bad memory issues. It's very subtle but I seem to have very low grasp on things I want to remember. My logical reasoning etc is very strong but when it comes to memorizing things I seem to forget these very very quickly and almost go blank. Please suggest some mild medicines/OTC supplements etc to help me cope better as it's affecting my IQ level in some manner now. Also, can you please suggest some safe medicines that I can once in while for deep sleep...I have trouble getting good sleep very very often these days and I feel hassled and sleepy all day long everyday.
