I am 37 and have had ADHD all of my life... I think the H is gone (I kind of miss it, need the energy) but my attention is about _________long...which frustrates not just me but my husband, children (who use it against me when convenient) and pretty much everyone. One thing that has helped me is having a PDA or smart phone...it has the alarms, calendars, tasks that you can set times for...it is a little expensive but it is worth it because you can get creative, like I have to work it down so far as to have an alarm 1 hour before school lets out....Also, another thing I have used with some success is having a DayTimer (I believe it is a brand name, but just a agenda and month book) especially the kind that kids use for school...I get different color paperclips and set it up so things jog my memory and I don't miss appointments... it is always a work in progress and sometimes things only work for a short period of time and then I have to switch things up, but I try and make it fun using things that are in the back to school isle and on sale (I'm cheap...wait that did not come out right...I like to save money) the color and cute stickers and such... Best of luck....I never say I know how you feel to someone because no one knows how someone feels, but I share your struggles
