While I cannot comment on your long term problem, you can boost your focus temporarily with a combo of L-theanine and caffeine. Works great when you take it after breakfast. Takes an hour to kick in and is effective for around 4 hours. Having a good night's sleep helps a lot when doing this.
For maximum effectiveness, do not try to multi task while doing this. Just think about the problem and let your brain sort it out on its own. Major difference with and without is the lack of tiredness of mind when attacking hard problems. Brain keeps hacking at it till a solution is found.
