the best way i can describe this is asking you to try to imagine waking up unable to speak.
so, you try to do what you want to do, whatever it is - and all that comes out are jumbled words. you try and focus, and you can't. you might need to communicate with a fast food worker to get a coffee, and you can't get the order out. or, maybe you're trying to communicate with a co-worker and just getting confused glances.
this is what it's like trying to read or write or create when you're involuntarily under the influence of drugs - you want to do something, but it's just impossible, or it can only be done slowly, or at a reduced rate.
i'm operating at 60-70%, if that.
so, it's like stumbling around at work with a lobotomy.
