You will want to break your fast with orange or grape juice diluted.
Since you have gone so long dilute it 25% juice 75% water at first.
You may feel improvement with one small pinch of Sea Salt on your second day of juicewater.
It tastes like crap (ccnutmilk) because its your body's way of protecting you from eating too much too soon. The juices suggested will stimulate your digestion to awaken and start again. You will start to feel restored and at that point you can increase your juice to 50/50. When that feels comfortable two solid fruits and water for your day will be your first solid meals.
Take you time.
