Oh, goodness! Sorry to hear of your back troubles! I am recovering from a microdiscetomy as we speak, pretty simple compared to a multi-level fusion. I hope it helps immensely with all of your pain. Best wishes on a trouble free recovery.
I would recommend an
istick or mvp as far as battery life. Could you get someone to take one home and charge to bring back to you the next day? Also, would they allow an atomizer in the hospital room (like those used for essential oils)? If so then I would invest in a cheap one of them and some peppermint essential oil and turn that baby on when you are
vaping. If they see the vapor they will think it's coming from the atomizer and the peppermint smell would cover the odor of the
vape as well.
