It's annoying once you get into a workout routine, and you feel good after your workout to having to cut it either in half or out completely. I'll be researching those supplements, and waiting to hear if they worked for my friend before starting anything, and my doctors appointment is before then anyway, so I'll be discussing the muscle pain with him.
As far as the craving mushrooms goes, TBH, if you're craving them, I would take that as a sign that your body wants that, and you should eat the hell out of them LOL. I've learned to listen to my body to a point... not always eating exactly what I'm craving, but for example, I know if I'm craving Fritos, that's a signal that my body is low on sodium and I need something salty ASAP. So if your body says MOAR MUSHROOMS I would totally go for it.
