I was having the same issue for a while. Here's how I resolved it : Stop working 18hrs a day on project (even if it's a startup), find other hobbies, meet people enjoy your life but be very productive in your 6-8hrs dayjob. The thing when you're too much involve in a project is that any deception, even something taht looks ridiculous will lead you to a lost of interest and motivation. Take a breath, take your time. A project need to mature in your head it's not a rush, it's a marathon (I know it's already have been told thousand of times).
