My husband is on day 4 of this program (started with Step 1) and has each day moved a new patch to a different spot on his body. Each place seems to cause pain and discomfort, an ache. Not itchy or red, just discomfort. He only smoked about 10 a day on average and I wonder if he is on the wrong step? He also said he felt slight nausea when being intimate but felt fine when patch was off. Any suggestions?
