How could you change your attitide? Do you have any methods in mind?
When you do your cleanse, do you have access to a juicer and organic produce? Make the extra effort to cleanse optimally. During the cleanse, can you get a shower filter (kdf)? They are inexpensive and last a long time. Then you can do some detox baths that will help alot. Also I think gearing up for a proper kiver flush will help alot and then onto a proper parsite cleanse. All the time maointaining a good diet. If yoy keep going back to junk foods, then you may need to look at some emotional/psychological balancing.
Healing is in your reach, but you truly must want it. ;-)
