What is it with men? estefaniasanchez, you sound like a very sensible person, checking BG to see if, or confirm a hypo is very sensible. 14 is a bit high, I went to 23 once and the emergency GP I saw wasn't in the least worried, possibly because he was not up to speed on his diabetes 101. I came to no harm anyway.
If it was 1.4 I would have thought, although not 100% certain, he'd be closer to going into a coma and fitting sounds like something else. He should certainly consult his diabetes team or GP or both.
My father has a habit of eating at 18:00 and not eating again until 10:00 the next day, an hour after taking his insulin, and wondering why he hypos. Pretty obvious really, timing is fairly important and I would have thought taking insulin closer to eating would be essential.
Hope you sort it out although I should be saying that he should take his condition more seriously and sort himself out. He's lucky to have you for a girlfriend/partner/other half (whatever the expression is these days).
