In this "instant" everything day and age, we may expect too much too soon from things like wellness programs...and then get discouraged and/or depressed when we don't feel immediate benefit.

Changes in diet, even if they are health promoting ones, and increased activity, while usually beneficial in the long term, are still stresses that the body and mind must adapt to. During that adaptation phase, some common symptoms of the body & mind's coping mechanisms are a temporary increase inflammation, increased need for sleep, changes in digestion, agitation, and mood swings.
The good news is that it usually only lasts for a couple of weeks...and you are already through the first one.

Hang in there. A change in ADs is well worth looking into; as your metabolism might be changing and you might respond better to something else.
