Hello Maxwellob! I am new too and I am learning quite a bit everyday being on these forums. As far as your metabolism goes I imagine that once you start cleaning up your body that it will start functioning normally. There are certain products I've seen that help with digestion. You should start with a Bowel Cleanse first, then the parasite CLEANSE. Actually I think they can be done together but me personally I would do a few weeks of Bowel Cleanse and then add the parasite cleanse depending on how well you are eliminating. The place I ordered from, RenewLife (www.renewlife.com) has products for everything. You can also look at Clarkia for the parasite cleanse. I am still waiting on my CleanseSmart. It should be here next week. I let you all know how it goes.
