It has stuff in to help you sleep so I would have to declare it at work and they would have to do a medicine check on it. It's a lot of hassle if you can just avoid taking it. Most medication has a 12 hour rule on it and we have to tell them if and when it's taken, some you have to be referred for further checks for. If we make mistakes at work they could be fatal ones so the rules are quite strict. Basically anything that makes you drowsy is a definite No. I did miss it last night though, I coughed most of the night and been coughing all morning. I can't have Beechams all in one at work either as it's 19% alcohol!!!
