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.
You may recover from Bell's palsy without treatment. Depending on how severe your symptoms are, you may not need much treatment, and you may never experience Bell's palsy again. For example, if your facial muscles are only weakened, your Bell's palsy is may be less severe than that of someone with complete paralysis.
