There is no "smoking" with vaping. Now you stuck on disposables, go to an open system device. These have better control of you nicotine usage than closed system prefilled from 0 nic options through 50 mg. You can work yourself down than being stuck in one prefilled pod or disposable.  Prefilled range from 1 ml to 10 ml 10-50 mg nicotine, so 2 days on the biggest disposables is not out of the possibilities. A pack of cigarettes on average is 240 mg nicotine you going 2 days. You are leaving 7356 other chemicals NOT KILLING YOU from cigarette smoking per cigarette.
