I have a good amount of 48 mg nicotine in vg that im thinking of freezing to further its preservation. I have never frozen unflavored nic myself, but i've done plenty of research on the subject, and it seems like people have a lot of mixed results. Im wondering how many of you have had your nicotine taste "off" after freezing, or noticed a decrease in potency. Please do not vote yes if your nic was past the expiration date.
