Y.,
Does this tend to happen upon waking, or in between meals? This can happen to me when my blood sugar is low...
Also, how is your anxiety management satisfaction level at this time? Do you feel you are getting results from the Lex? I ask b/c I have also had shakiness simply as anxiety sx.
So, as Gilly said...certainly ask your dr., but don't worry about
this, as it is surely easily explained.
