Good morning Lila,
Glad you had a nice trip. Too bad it was so cold out.
Like you, I really miss my bulletproof coffee when I travel. I ordered MCToil in capsules from the store where I the oil. They are a large soft gel and I just swallow 3 or 4 of them with my coffee. No fuss, no muss, no bother. Easy and light to stick in a baggie.
Not quite the same as the concoction with butter added, but good enough for some of the benefits. 3 soft gels contain 3 grams of MCT oil and are about a TBS of oil.
You can also order this from iherb.com.
