Our reactions to differant drugs are not all the same, what is considered to be a low dose of Neurotin, knocked me rotten and so did Oxycontin, but a daily total of 600 mg of Tramadol & 175 mg Endep worked perfectly for me with no side affects except a bit of a dry mouth from the Endep, which was easily fixed by chewing gum.
I hope you can find the right combo that suits you.
