Hey, I m quitting smoking currently and experiencing some serious fatigue, trouble concentrating, skull-splitting headaches, dizziness, and generally feeling like crap and out of it. I m on day 19 of Step 1 (21 milligrams) of the Nicoderm CQ extended release patch. I smoked about 20 cigarettes a day for the last 3 and a half years, with extended periods of heavier smoking of about 30-40 a day. The instructions for the product say individuals who smoked over 10 cigs a day should use the 21 milligram patches, but that dizziness can indicate nicotine poisoning. I highly doubt I m dealing with poisoning, but I can t find much info about whether or not quitting can cause vertigo symptoms this far out (especially if I am still getting the nicotine via the patch). What s up with this dizziness business?
