Think we had this discussion in the thread I created, however if you want something to help you get to sleep after a shit shift (I know, it's so absurd, but your body compensates for lack of sleep and runs your metabolism at full pelt to wake you up) I would suggest this:
Phernergan (promethazine) 25mg tablets and you can get them at
any chemist (even Boots), but you have to ask as they're not on display. Promethazine is an old fashined anti-histamine, however it has very minimal sedative effects, so one or two 25mg tablets will absolutely help you drop off a lot easier, Daz.
It's not addictive, I promise you, and it's not harmful. It's just an old fashioned anti-histamine that the GMC found had benefits of helping people sleep better.
Please try it, because it's helped me a lot.
