I will be 91 this summer and have insomnia due to pain from arthritis and pins and needles pain in my hands. I take only acetaminophen at 7 P.M. and 1 A.M., i.e., 2 caps of 500 mg each. I have had very bad results from prescription meds, i.e., dizziness and heavy malaise the following day, so I avoid these meds. Which prescription meds have the least side effects? Are there highly effective external creams or lotions? Thank you so very much. YYYY@YYYY
