Like Graham says, any money you take out of the business are Drawings and this reduces the Capital a/c (or Owner's Equity a/c etc).
If you add extra money of your own into the business, that would increase the Capital a/c.
I do my own accounts too, using QuickBooks. If I put money into the business, I use the Capital a/c. For Drawings I set up 2 accounts: Drawings (Personal) and Drawings (Tax) (for the big payment to the tax man each November!) but that's purely for my own record.
At the end of the day, as a sole trader, you are not legally required to use any set format / account names within your accounts as far as I know. You just need to keep full records of everything, and have figures to hand to do your tax return each year. Once you know how much in total you took out of the business in the year (Drawings) and how much Capital you added in, that's all you need to fill out in your tax return.
Of course, if you ever intend getting an accountant, it helps if you keep a fairly standard set of a/cs and it also makes doing your tax return a lot easier as you can just copy the necessary figures directly from your Profit & Loss statement and Balance Sheet.
