i print calanders off of my pc before I start my cycle and map things out before hand. It really seems to help, you know what to take on which days and you won't end up using too much or too little. It is especially useful on the more complex cycles when you are changing your drugs up or using compounds that you have to inject evd or eod. helps me keep track of when to start clomid and I also know when I changed things (if i did)...Just a little tip as it has been very useful for me...
