I've been very forgetful lately..?

Your husband makes a good point. I experience the exact same thing you describe OFTEN, and it is not the result of some brain abnormality (as I've had an MRI and EEG recently due to headaches). Don't add to your stress by jumping to the conclusion that you have a brain tumor dear. Sometimes we just have to accept the fact that the rush-rush of our daily lives sometimes becomes just a bit too much for us to keep up with. It may be a case of your level of concentration suffering as opposed to having a 'bad memory'. There is a distinction there if you think about it. We can only deal with a limited number of 'things' simultaneously. We just can't divide our attention indefinitely right? As long as this is just an aggravation and not a possible danger to you and others, don't worry over it.
