dude, you need to read my post and get some raw unsalted pumpkin seeds and cloves, as well as a good laxative (castor oil, cascara sagrada, senna). make sure the pumpkin seeds are raw and unsalted. the cloves need to be fresh whole cloves, the stuff in your kitchen pantry wont work. i am about to do this method with other herbs. i took Wormwood tincture by itself early this year and it did nothing. felt a little weird but didnt pass any worms. Wormwood doesnt kill the eggs, thats what you need the cloves for. everything i've read recommends the Black-Walnut hull and Wormwood + pumpkin seeds + cloves as the way to get rid of them. search for natural remedies to eliminate parasites.
your case sounds a lot like mine and i wanna make sure you dont have to suffer for years. all those symptoms are like me and i noticed it around the same age. when it first started being noticeable i had no clue what was going on. you are lucky that you came here first and realized you probably have parasites. i've lost half my hair in a span of a couple years, its awful.
1 bowel movement a WEEK is terrible, to be honest i'd go see a doctor ASAP if you have health insurance and tell them that. something is definitely up and you need to check it out.
