You can do it! Just jump in there and get started. I didn't have a partner until my 5th day. Once you get past the first 3 days you'll be pretty much set to achieve your goal of 10 days. I'm on day 7 now. The 4th and 5th days were energetic and great. I over-worked myself on the 5th day, so I was weak on the 6th. I think a little weakness is normal in the mornings. Just try and take it easy while you're fasting. Now, I'm on day 7 and day 10 seems right around the corner. It feels like I can easily accomplish that. Just my experience, but it seems pretty true to form on from the info posted here. Happy fasting!
