Hi. I'm looking for advice on stopping chain vaping. Jittery, strung out and not sleeping! Mood swings! Seems increasing nic strength just increases tolerance and vaping just as much. Tried a bit of a friend's Umba WTA that he brought over and... Wow! And 6mg instead of the 18mg normal nicotine! Expensive to order in SA, so wondering if anyone has advice on if WTA is the way to go to stop vaping ALL the time, before investing. Thankfully they sell big bottles of their WTA in menthol! Thinking I can get some to add to our local ejuice. Are there other WTA vendors that also do a plain menthol? Any advice would be great!
