Was just diagnosed with Bell's palsy and getting married. How can I get mouth to turn up for wedding? Would facelift tape work?

I'm taking prednisone and antibiotic for sunus infection (second one in two months) Also taking some supplements (B vitamins, Lysine, MSM, DMSO). Using artificial tears, a heat eye mask. It's possible may resolve by wedding, but if not want to at least like to not frown at my wedding. It's a second wedding and no spring chicken (I'm a 61 year old widow), but do want to look decent. Turned down mouth main concern
