Are all the reoccurring problems/symptoms that I keep crediting to my thyroid disease or hypothyroidism actually reoccurring symptoms/side effects of methamphetamine use? My thyroid has been checked twice in the past 9 months and my hormone dosage has not been changed. I have dry skin and brittle nails massive weight gain (after my revival breaks), and during each break incredible tiredness, oh and my all too wavering period, will it come or not.
