As someone with ADHD and who also works from home 4 days a week, alarms are your friend. I have specific alarms set for tasks i need to get done every day aside from my main duties.
Depending on your job, setting up automations can also help. Anything to make your life easier will give your brain more bandwidth which ive found helps me focus better. For me, i have a script that automatically refreshes a webpage that i need to monitor all the time. I always keep this tab separate so that when it does refresh, i almost always notice.
Ah yea i see how that would be an issue. Someone else in this post made a comment about switching meds. Might be worth talking to your doc about it.
That said, its not uncommon for those of us with adhd to try to find dopamine when doing things we dont wanna do. Sometimes having a video on in the background can help and distract your brain a bit. The key is finding something that doesnt distract you too much.
Stuff you watched before can be good.
