Another 2 cents ...
Too much nicotine and/or toomuch menthol gives me heartburn with my e-cigs.
I was a pack a day, salem light 100s smoker prior to ecigs who, like you, really only had heartburn when I was pregnant.
I started at 24mg and dropped (quickly) to 6mg with the heartburn ceasing. However, I have recently gone up to 12mg without any issues and have successfully beat my analog cravings.
I figured out the menthol part after adding to much menthol crystal/liquid to my own juice
For the record, I am not a MD but a RN and none of this is medical advice. Just sharing personal experience...
