I take Lyrica 150x2 and Tramadol, 50 am and 100 pm, for pain espec in legs and feet. Since taking the Tramadol I have extreme weakness, dizziness, espec when standing from setting position, trouble breathing, severe sleeping problems, sweats, memory problems, constipation/diarrhea. What can I use to replace the Tramadol and eliminate the previous conditions. I also have Prostate cancer and just completed radiation--5 days a wk for 9 wks, along with one injection of Lupron. Thanks, Norm Wells
