I'm on day five too... I totally understand the urge to quit!!! This is really hard. I hear that the first five days are the hardest - I'm clinging to that! I look at my maple syrup supply and say to myself "I can quit when I'm finished with it". Hopefully, I'll be better motivated then.... but ahhhhh food. I also am planning for my soup and all the things I can eat.
Don't be disappointed with yourself. I think five days is a great run! Hey, if you do start up again, at least you'll have some "content" to expel :)
