i know my meds cause drowsiness, it says it on the pack. i specificallky take one dose at night knowing i wont be going out. and if i'm workjing nights i swap them round and dont take the mirtazapine cos i cant stay awake.

however, that said, if something did happen potentiually i could lose my licence as i've not told the dvla i take them! i wont cos i know they'll take my licence for a while and i need to drive for work
