Pregabalin taper

I’ve only been on 150mg pregabalin per day for 5 days for post herpatatic neuralgia . I want to come off it due to the horrendous side effects of dizziness, blurry vision and feeling like I’m in a drugged state (which I am of course). I can’t drive like this or function normally.

I messaged my GP early this morning, but have had no reply so far.

I missed out my mid afternoon 50mg dose, but really don’t know whether to miss my 50mg evening dose as well. Am I likely to suffer withdrawal effects if I go cold turkey?

Thanks in advance.
