One of the symptoms of this distressing disorder is chronic diarrhea which can have a green tinge. This is because with the gallbladder removed there is no storage facility for the bile and so it is constantly dripping into your small intestine. The causes of diarrhea cannot be determined by the color alone. The fact that your diarrhea is green says more about the fast transit time than anything else.
People who have trouble sleeping may want to use magnesium supplements to help. The right dose may fall between 200 and 400 mg/day.
Some people also seem to develop a tolerance for valerian and it stops working for them after a while. If valerian doesn't work for you as a sleep aid, try taking 250-300 mg of magnesium along with 300-600 mg of calcium citrate with a full glass of water an hour before you go to bed. I've had good luck with this combination so far.
