The more I read, the less I feel this could be an issue for me.
I know we can react to fillers in meds. Often times when a person reacts to a med and calls a company, when asking about the fillers, the company will have no idea what's in the fillers. To me, they have no business listing the med as gluten free if they do not know what is in the fillers. This has happened to me more than once. Just as your daughter takes a tiny dose, that is what I think I should do too.
I walk every day without issue. Well, my feet hurt and sometimes one knee, hips...yet I keep going. Neuropathy can do that to a person.
I think my fatigue was gradual, but I have had fatigue for so many years now, I'm not sure anymore.

The fatigue as of late seems much worse, yet I can't say if it came on fast or not. Not much help am I?
