Currently on holiday I used patches for the first week and an e cig occasionally. I have run out of patches so am using my e cig more not sure if it's related but I now have the most horrendous wind is this a side effect? New to this. Was previously a bit constipated but that seems ok now but the stomach ache and discomfort not to mention embarrassment of this wind is awful help is is connected to me using an e cig
