Thanks everyone for your advice. I will check out all the websites you suggested. Ruth you did mention something that really caught my attention. You said that it may be connected to liver/spleen/colon issues....I suffer from constipation so this may be the root of my problem! Laxatives don't work well on me and the doctor prescribed some colon cleansers but they don't work either. What do you use to cleanse? Once again thank you all for your advice and I will be looking up those websites very soon!
