I've had a bad cold the last few days and bought some sinus tablets yesterday afternoon so I could sleep at night.
The pharmacy advised not to take them too close to bedtime as they might keep me awake as they have some sort of stimulant. And so I stupidly took some at 10pm 
It's gone 4am, I've been lying here wide awake since 2am and I need to be up just after 6. Both kids have migrated to my bed and are taking it in turns to kick me in the side (one lying either side of me taking up most of the bed)
What I don't know is, is lying still and resting anything like sleep? V worried about being able to function tomorrow (longish drive to work at 7am then full day at work)
In other news, my sinuses are totally clear 😒
