Enema. I know if you haven't done this before you may not like this answer, but it truly is an immediate relief to your constipation problem. Use 4 cups of water (preferably distilled or filtered) add the lemon juice of 1/2 a fresh lemon (this helps get things moving) warm slightly to a comfortable temp. (not hot) and with an enema bag SLOWLY allow half the water at a time to enter. Sit on the toilet and let it all come out, then lay down and do it again. Sit on the toilet and let the rest come out. Do this every day you can and you will also have nicer looking skin since the toxins will be going out of you and not being deposited else where.
Also you mention you are taking the Humaworm after lunch and then at bedtime. I will take it when I wake up in the morning with a large glass of water (or two) and not eat for at least a half hour or a whole hour and then I take it about 8 to 12 hours later at least 3 hours after eating anything and 30 to 60 minutes before eating. Empty stomach is the key.
Hope this helps.
