Please Help Me. I really need an answer?

I have been researching hypnosis for help with finding a lost item. and it has been like two years since losing it. I know that lost it on 11/3/06 and I know that I need to remember some details. I can't remember what I was wearing that day but I do know the last time I saw the item. What other details do I need in order to tap into those parts of my subconscious mind. I really hope that the hypnosis will work it's my only other option to try to find this object and I really need to.
