I did not have extreme anxiety during WD and sleep was about the only thing that was hardly affected... though in the mids of WD, now 3 years ago, I sometomes got up in the middle of the night to smoke... My sleep is fine now though I am overall a bit tired and that is IMHO still WD related. Anxiety is now mild to moderate but this was an original issue for me and very effectively oppressed by the Paxil.
The eye issues is hardly to describe, no focus problems and my eyesight is fine. It is just the feeling of pulling at the muscles and nerves. It is related to the jolts in the chest and even the tinglings in the arms.
The drug, though the first years pretty effective, really made minced meat of my CNS but if I can recover from that, I think everybody can.
