Short Term Memory Loss

I've been having memory problems lately. I takes me a long while to remember stuff, and if you introduce someone now, in a few minutes I would forget that persons name. I tried taking vitamins for it, dont think it worked. I talked to my friend about it, he told me its because of stress and lack of sleep. I now totally agree, work stress is getting to me , and this stuff worsened since I got promoted. Some people get pimples, highblood pressure, hair fall, I get memory loss. A few minutes ago I figured out how to cure my stress problem ... now if I can only #@$@#$! remember what it was.
