Orangina'ed to Death.....

Good grief, I swear I will go entirely round the twist before I finish this Orangina.  I have been able to knit (kind of.  Well, the VERY basics) since I was about six.  Never took it any further than scarves.  Until now.  Yes, I know - it's taken a while (34 years actually).  But we do have progress.  I have completed my first pair of socks, having ripped the first sock apart at least eight times (honestly) as I just COULD NOT understand what the pattern was getting at.  Of course, once I understood in principle what I was supposed to be doing, it turned out to be easy peasy and now I'm trying out a simple pattern on a pair for Charlie Townes.  Luckily he does have small feet.  But back to Orangina.......  Recently I have been thinking that maybe the combination of: staying at home under increasing pressure from the demands of a (sometimes) tyrannical toddler, my age and whatever secret activities my hormones may be up to, lack of available intelligent (or at least intelligible) conversation and a few other things, hold on , I've lost my thread.........You see what I mean?  The combination of all those things has done something to my brain power.  It honestly feels like my brain is coated in a sort of gooey golden syrup or something.  And trying to knit Orangina has almost finished me off and I've only completed a few inches.  I just cannot concentrate on the pattern long enough not to lose my place after about 4 repeats.  What is wrong with me?  It is not complicated.  It is rather a pleasure to knit.  But I'm spending most of my time wondering why I have one stitch less etc... and every time I have found (after unpicking rows) that I lost my concentration somewhere and did K2 tog twice, or some other nonsense.  Tell me, is this going to be a slow demise?  I obviously need more omega 3.  Just off to get some.
