is he taking the l cysteine with anything else or just the pills? I purchased those for a parasite cleanse but I dont intend to do the cleanse for a while. Although that does sound promising it costs like nearly twenty dollars here for a bottle of 60 so is it really worth it for three days? I would probably focus on why its working and what he can do to help stop it. Thanks for sharing though I will keep that in mind. Keep us posted.
