parastroy and constipation

Until I can get these better drugs ordered I am going to take a parasite killer i found at a health store called parastroy. The problem is it says dont take while constipated and this seems to be a never ending battle. the stool softeners help but I have to keep taking them or i dont have a BM. is this safe?they are in mostly in my spine and head. I would think the parastroy should help but I cant see a specialist(who probably wont help me either)in infectious diseases on the 14th. Also does anyone else have a hard time eating because the parasites make you feel so awful and give you anxiety? I have lost maybe 15 pounds in a week and a half Tweet
