Oh, another issue. Your commute is never deductible. So the only mileage that would be deductible is how many extra miles you had to drive because of picking up and dropping people off on the way to and from work.
You may be able to get around the diary requirement in this particular case assuming you know which days you worked, and if you have records or remember where your clients lived. You can figure the mileage difference using google maps or a similar service. You would need to write down for yourself as soon as you can, while it is fresh in your memory, a list of each day you worked, who you picked up, and how many extra miles that was for that day.
