I'm ok today. Thanks guys for your replies and concerns.
I've just woken up but slept soundly through the night.
The effects continued to increase last night, it was like I was really drunk; I couldn't walk without falling into something and my speech was slurred. But all the while I did remain coherent in my cognitive thoughts.
I will keep them to definitely use only as required. I didn't realise how risky taking so many is... I guess I was thinking of them like Valium, my usual thing, of which I often take a lot of at times; never 22, though!
I'm still a little wobbly on my feet and lethargic today, but I'm fine x
