When using the form you can fill in as much or as little of the information as you like. When you hit submit a file known as a Google Doc will be generated in your name. The new document will be added to every time you enter new data and hit the submit button, an email will be sent to you with a link to your data. The advantage of this is Google docs are available anywhere at anytime as long as you got an internet connection. The data which resides online or can be downloaded into an excel spread sheet can be manipulated in any manner you wish. You can do post meal averages, fasting averages, the effects of insulin or track anything you desire. I can also provide limited assistance in helping you manage your google doc.
