There have been two posts recently about spider veins after flushing. For some reason, perhaps a nutrient or vitamin deficiency your veins are fragile, or maybe you have a Vitamin K deficiency. People with this deficiency bruise very easily so just the pressure of sleeping on your left side or slightly abraiding your right rib area may have caused this.

Vit. K is made in the gut by bacteria so if your intestinal bacteria are unbalanced they may not be making enough for you. Are you doing the flushes and not allowing your body to recover between flushes? It takes several days for my body to adjust to the different balance of bacterial growth in my gut and to eliminate the toxins released. I take either probiotics or goat's milk yogurt for the 'good' bacteria.

I wonder if your coated tongue could indicate a yeast problem - Candida or one of the other yeasts that can overgrow in your intestinal tract. There are lots of remedies for this online - I am using Kroger's Candida Formula # 2 and Neem leaf capsules. Apparently the Candida started overgrowing after I took Antibiotics about 2 years ago and I didn't realize it was causing the problems in my gut.

Hope this helps.

i don't know about the spider veins. i have noticed one of my eyes is usually a little bloodshot after a flush. i don't know why and it clears up in a day or two.
the coating on your tongue is probably due to a release of toxins. the same thing happens when you fast and your body starts releasing toxins. so i wouldn't think of it as a buildup of toxins as much as a release of them.
you might try castor oil packs over your liver to see if it helps with the veins.
and make sure you have done a kidney cleanse to help eliminate the toxins being released. other things: liver herbs, chlorella/spirulina (to help remove toxins), weekly one day fast
