Well, damn, spoke too soon!! Seems now nearly all my ce4's are tasting chemical and strangish now. It's now too near xmas to order a protank, also I have no cash right now, so I will have to wait till january to order a protank. SO, in the meantime until january I am stuck back on the cig-alikes which I first used when starting vaping!!! Going to be a long hard xmas season!!!! Oh well, hopefully I will be able to stay off the cigs with the cig-alikes!!........should be an interesting time!!!!.....
