I hear ya Gwenny, I'm 1 week sober...
I've been trying to study Behaviourism and instrumental conditioning (the whole rat in a maze kinda thing) for the past couple of hrs and I think i've read about two pages. I can't focus and I'm having to read the sentences about 5 times over.
That whole static fog is doing my head in.
From what I've read it will pass, but it's different for everyone.
Are you taking any vitamins? B complex is supposed to help.
Some fresh air might help too? I'm off for a run with the dog and my mrs in a bit then hopefully I might get a bit more done this evening.
I hope your 'fog' gets better soon, I have a few more weeks to finish reading this and another module and hand in two essays...urgh
