Dry lips and skin are a sign of low thyroid and gut fermentation. You need to first eat a lot of fiber from raw fruits and vegetables. Normal number of bowels paper day is 3-4. If you are not pooping you have lots of other issues to follow.
I agree with Tayto, Liver Flush and Iodine will help. Have you taken your basal temperature? If not, please do, you can search for it on CZ search. If your basal temperature is above 96 then you need to look at your gut and do a colon cleanse, kidney cleanse and then liver flush. Don't be afraid of liver flush, just read and be prepared and ask questions here on Liver-Flush forum. I rather do that vs. taking drugs and other supplements.
Eat raw foods and you will be fine. All processed foods are staying in your colon and not getting out.
