Yeah I agree with
@Sir2fyablyNutz, you should be fine.. Nicotine-fiend me probably woulda smoked through the stomach bug, depending on the severity.. Although, it sounds like you've actually gone longer than 3 days with the sickness, you've just been symptom-free for 3 days. I'd guess you're totally in the clear at this point. If you're very concerned it could be worth asking your doctor.
I'd definitely suggest toning down the nicotine level if you can (or want to), as it's a good opportunity to wean yourself off a little bit. Although, I shouldn't talk, I've been vaping for 2 years and I still have 6mg/mL nicotine in my juice. Just a point worth noting.
