Bell's Palsy does make you feel fatigued and your strength should be back soon. You've had it for a month and a half now so give it some time. There isn't a cure for this so we sometimes try anything to help alleviate the pain or symptoms. Sometimes, it works.
Recently, I experienced sickness related to increased stress in my life. I had facial paralysis and at the tender age of 35 I believed I had a stroke because of the initial symptoms I noticed. I was not, however, having a stroke. I was experiencing a stress related disease, Bell's palsy. Bell's palsy is a disruption of function of the cranial nerve. The cranial nerve controls facial movement. An untrained eye would view the symptoms of Bell's palsy as a stroke. The face doesn't respond in a normal way. The mouth does not like to smile.
