Sometimes when I had those unsatisfied moments I found a brand new atty helped. The old ones decline slowly and after awhile...just something lacking.
Also, switching up juices, voltages, devices, etc. can bring you back to your happy place.
I can say that at my 90 day mark I lit a smoke just to see how I'd react. I could not put it out fast enough, the smell & taste were so awful...washed hands, brushed teeth lol. It's not smoking I was craving but better vaping.
The Cisco LR306's were game changers for me. Most full and satisfying puffs I've had over any atty & carto I tried previously. Still after one starts to get weak I notice I'm not quite satisfied but slap a brand new one on and I'm back in my happy place.
Good luck! It is a process
