I have narcolepsie and take methylphenidate to stay awake in the day. I will have to take some if I don't want to have my face in my supper but since its a resto-bar, of curse there is alcool after, but I was wanderring if I really had to wait that the effects had finish of the meds. or if I could take some if there was like 1h left for the methylphenidate to finish(mine last 4h by the way).
