I keep finding myself losing focus in the middle of doing even basic maths. I sometimes know exactly how something should be done, but make stupid mistakes doing it because I can't fully concentrate.
I used to have an obsession with numbers (as a kid) and was great at mental maths. Now, I'm just meh, because 'careless mistakes' slip in.
Just now, I had to calculate the sum of three sets of two brackets, each with three terms [something like (x+2y-z)(-x+y-z)+(-2x+y+z)(x-y+z)...]
I did each set of brackets one at a time, but the first two I expanded wrong. I kept forgetting things and so on.
I also found that when I once accidentally overdosed on caffeine, I got the highest score in a practice paper for a test I needed to do than I had ever got...
Does anyone else have this problem, or has anyone solved it? Please give me any tips you have.

(Also, I know sleep is important. I haven't had quite enough at the moment, but I really struggle even with an average of say 7.5 hours :/)
