I've been experiencing nearly the same withdrawal symptoms from regular high grade marijuana. I'm 10 days sober and just now starting to feel a little better. The anxiousness has been the worst, and amplified by being hungry but having no appetite, like you said, food just seemed to dry up in my mouth and made me gag, a couple times even get sick. I actually ate a piece of chicken yesterday which still was not enjoyable but it felt good to eat, chew, and swallow food without feeling sick. Trying to focus on the ways life is improving instead of letting the anxiety get the best of me while I sober up. Thanks for your post!
