Can you grow past 18?

Ok, so here is the question. I am 22 and lately I've been taking my vitamins again, I have lost a lot of weight and I feel taller all of a sudden. I look in the mirror and I look lankier, people have also told me that I look like I've grown a little. I am so confused, I thought men were supposed to stop growing at 18. I stumbled onto this Medical website that stated that there are rare instances where men have had growth spurts as late as 23, can I be one of them. Please, I need an answer.
