Switching to Paxil from Effexor 225mg for anxiety and physical symptoms?

I have been 2months on 225mg effexor and my body feel on edge all the time ... I cant even watch a movie without feeling intense need to do something else and I feel hot and sweaty all the time I cant even sit myself and relax I hate it and lets not talk about the nightmares and the insomina aagh

I take 5mg clorazepate prn and it helps a bit

I am consedering switching to paxil cz my neurologist mentioned it before as the best med for physical anxiety and stressed bodies
