get your eyesight check, at some point in life I was having difficulties staying focus and even started having headaches... and I needed prescription glasses...

Also very important, try to sleep the best you can and do exercise... I remember reading here about exercise in some cases exceeding the benefits of ADHD medications...

If you are overdosing things... don't... caffeine can be overdosed and the effects are nasty and lingering... caffeine is meant to be a zero sum game, where it gets you speed in the morning and when it wears off then you go to sleep... if you over dose it then you are making your body over exert and at some point the body will communicate the results via extreme tiredness, bad humor, etc...

Don't be hard on yourself, from everyone we are the most hard on ourselves when we should be the most kind of them all.
