Would you anticipate this being a problem? I would only be taking a small amount on holiday for personal use, but do not have a prescription. Am I likely to have problems at customs in Barbados?
If u do that treat it like u were smuggling coke or something: Extreme caution. I wouldn't recommend it tho. If u aren't going to be away more than a week or two just take a break from th gh. No prob in that.
