I have been taking Elavil and Celexa for 2 years and my doc put me on Toprol about 6 weeks ago, because the pain kept raising my blood pressure up and down so fast he was afraid I would have a stroke...I haven't felt this good in the two years since I was affected by RSD...I think everyone is different. My friend Marsha has a really hard time with the Elavil and I am highly allergic to Lyrica and it works great for her...

Good luck with the med change
