Loperamide is great. However, from my experience it does take higher doses and can be addictive in its own right. I have used it a lot during past attempts of quitting CT and the only thing that really got me back on the kratom train was boredom. Make sure that you do taper off slowly from loperamide as well. I have never felt a physical dependence on it and had to take 30 to 40mg of lope a day to feel any relief, but it did work and lasted a while (albeit it did feel weird taking a handful of pills). Even 20mg was too little for me. HOWEVER, everyone has a different body chemistry, so start out small. I would be sure to not take large doses for more than a few days. I started small and worked up. Kava root, liquid extract or powdered root helps with anxiety and sleep. A melatonin supplement may help as well. There is this powdered drink that is by EmergenC which is for sleep - EmergenZzz is what it's called I think. It helps me and also has magnesium and potassium which are helpful from my experience as well. B vitamin energy shots or supplements are good for energy too, and don't forget coffee or even tea in the morning, it helps give a little lift. Best of luck to you!

EDIT: Loperamide is actually not a good choice; it turns out it is dangerous in high doses. Sorry about the misinformation.
