I smoked for a week after starting to vape so had no need to chain vape.
I expected to vape like I smoked but that was not working out. The frequency of vaping compared to smoking was probably the oddest part of vaping to get used to. A decades old routine had suddenly changed.
I soon found this forum and learned that folk did not vape in the same five minute bursts like smoking, so by the time I stopped the fags I new to vape as much as I needed, when I needed, so was happy to chain vape when required and soon got used to it.
These days I use different nicotine strengths to fit in with what I am doing at the time. I am happy to chain vape lower nic when not doing much and at other times grab a blast of higher nic when busy or chain vape high nic before a few hours without vaping.
