I have heard of people doing the following for natural remedies: mix 1-2 Tbps ACV in 8-10oz water, drink this x3 a day: Oil of oregano under the tongue (diluted in coconut oil) 3 times a day. AHCC, 3g per day for 3-6 months (study in progress on this). Check out earthclinic.com for more. Its sort of hippy'ish, sort of weird, but also sort of interesting site.
Hey did your symptoms ever go away? I'm feeling the exact same and am worried. Any update on your situation would really help
