From how your phrase the issue I'm a little concerned that you may end up with a nicotine O.D. vaping at 36 mg if you don't understand that this does not work the same way as smoking. There is no instant rush from vaping because the nicotine absorption is done primarily through the mucous linings in the mouth. It's a much slower process and similar to how nicotine is absorbed from nicotine gum if you ever used it - by the time you felt a craving it was too late. You can't make up for the quick and dirty method of absorption done by smoking via higher nic level liquids because 1.) Smoke is primarily absorbed by the lungs. and 2.) You are missing a lot of ingredients that come along with burning processed tobacco which contribute to that fast rush from smoking.
Still you may need a higher nicotine level if you are having serious cravings. But if you are expecting to get a cigarette rush from vaping that isn't going to happen, and chasing a really high nicotine level expecting it really isn't a sound thing to do. If you have recently quit and vaping is a new experience you simply may need to work at vaping more. It's not an auto-pilot thing like a lit cigarette - you have to pick up the pv and press a button every time you want a drag. In my first few weeks I had to work at actually vaping enough on a consistent basis, rather than just chasing cravings.
Personally, I started with 26 mg and didn't think it was enough. I bought some 30 mg liquid and only used it during bad craving problems - morning mostly - and dropped the 30 mg stuff after 90 days. But incorporating 30 mg liquids was done out of a need to deal with pretty bad withdrawal symptoms from smoking, not as an attempt to replace the instant buzz I used to get from a cigarette.
Just be careful and understand that this is not smoking - don't expect it to be the same experience.
