I have this happen to me a lot. The funny thing though, is that in relation to children by age, they suffer the same problem as well. Kids these days are largely attached to electronic devices, and it isn't anything against them, its just the availability of it and the large amount of entertaining content available. I think you are really just subjugated to the same mind addiction that all kids and adults have to deal with when it comes to technology. Also, I have read that the light can affect your brain, making it hard to sleep for up to an hour after leaving a screen, so I wouldn't be surprised if there is a bit of an addictive side effect from technology, it kinda is for me.
I think the solution is just making a self regulated schedule, or care taker regulated if you have one. It could be that you are not allowed to use technology after a certain hour of the day, or after a certain number of hours of use. Give yourself a timer and then force yourself to quit. Another idea is that you could say you have the same time limit, but after that time comes, you can only watch shows, which still allows you to be entertained, but also interact with your toys. It really is just going to come down to self control methods, or self parenting. I think that you will find that you still really enjoy your toys when you give them the time to play with them, but if you don't consciously make an effort, technology can be addictive.
