You should be having 2 to 3 BM's per day. You mentioned swollen lymph nodes. You definitely need to cleanse your lymph system. This is real easy, do dry skin brushing everyday over every inch of your body and/or do rebounding (mini trampoline) for 5 to 10 minutes per day. Drink lots of good water and add some fresh juices and nutritious foods. Avoid sugar, caffeine and alcohol. And DON'T take ANY vitamin C BEFORE your appointment.

Vitamin C will negate the effects of the novacaine and will cause you to feel pain. Get on a good probiotic, this will help tremendously with your Candida. A great one to get is made by Garden of Life called Primal Defense. It's a bit pricey but worth it. You can also add some yogurt or Kefir to your diet to get beneficial bacterial.
