In my experience, yes, a slightly off level can cause major symptoms, I doubt it does in everyone but it does in me and possibly in you.
Range can make a difference, T4 free should be in the mid to upper part, if you are in mid range and do not feel well you may need to be in the upper part of the range to feel well.
