So constipated.

Please, please tell me the secret to pooping like as soon as possible. It has been seven days. I have tried it all - Metamucil, fiber capsules, maximum doses of Docusate, glycerin suppositories, coffee, massage. Today I have had 60mL milk of mag. No results. I drink about six 8oz glasses of water per day and I am relatively active for work. I feel really at a loss for what else I can do.
