Hello,
I would like to congratulate you on maintaining abstinence from alcohol successfully till now and wish you can keep it up and help others too.
Seizure causes
brain injury, however it would not cause forgetfulness after two and half years now.
As you yourself suggest your forgetfulness is more of a result of your will of not to pay attention towards issues. You should be more attentive and careful about the things in your life which demand your attention and your forgetfulness should be taken care of.
Another reason of forgetfulness can be Depression (
Pseudodementia of depression). If you have any of depressive features like sadness of mood, decreased interest, decreased sleep/appetite, death wishes then see a
psychiatrist.
Then there is dementia which happens in old age. If your age is more than 60 years you can get yourself consultation from a Neurologist/Psychiatrist for Mild
Cognitive Impairment. Also check for blood levels of Vit B12,
Folic Acid, Thyroid Function Test.
Some methods to keep your memory strong are cognitive exercises (solving Mathematics problems, Sudoku, Puzzles), healthy diet, regular exercise, good sleep and meditation.
Hope your concerns are addressed. Feel free to ask any more queries. Take care.
Regards.
