I've recently been on 16 SF a day with other herbs. Yesterday i woke up after 8 hours sleep and felt so exhausted. Today I woke up with a scratchy throat, which turned to a really sore throat, dry cough, post nasal drip, headache, backache, neck ache and, now, laryngitis. I am almost giddy that this could be die off and that the protocol is showing signs of movement for me. I do not know for sure if it's die off, though. I am a little sad bc Matia had me stop the SF for now and I feel kinda like I want to keep going and keep things detoxing! Ha ha! I called out sick from work, flew home, and now have the next week off to rest and feel crummy. I am okay with it. Especially because there is no nausea...yet. I am hopeful this is not just a cold, so fingers crossed. Can anyone shed light on if this sounds familiar? Also. I just feel so exhausted, like my eyes have bricks on them. I only slept 3 hours last night which could be why, but just generally feel lethargic, achy, very hungry, and really uncomfortable with lower back pain. Hooray!
