I'd recommend checking 'Dopamine Fasting'. It is a deliberately catchy title, no, you don't/can't abstain from dopamine, but the content is rock solid in terms of taking breaks from over-stimulation loops.
I personally try to mimic no-electronics "sabbath"s on Sundays (no religious affiliation). It is not as harsh as it sounds, just away from fast reward loops of apps and internet to more long form content such as a 3hr podcasts, an actual physical book, wandering in nature, conversing with people important in my life etc. Also feelings like loneliness and anxiety can present as overuse of tech, so I take that as a sign to double down on healthy self-care basics such as meaningful connections, adequate exercise, outdoors, sunshine, whole foods, laughter etc.

I personally recommend you don't, based on my half decade, personal experience until about a year ago. Yes it will increase your task salience and perceived energy because your brain will be swimming in dopamine, but you won't have the matching wisdom to pick your tasks or use that energy appropriately. Believe it or not, feeling bored or not motivated is a crucial part of picking what we spend our energy on so that we can achieve meaningful, sustainable long term goals. Psychostimulants bias your sense of bio-economics, everything has a lower threshold of feeling like a good idea to do. You'll read reports of people cleaning their houses or masturbating all day on therapeutic doses (Yes these are outliers, but it exemplifies the class of errors you'll be liable to make on it.). Also over time your dopaminergic systems will physically downregulate to adapt to exogenous stimulation, in which case operating without meds will be harder and harder.
Obviously your current state don't seem to help achieving meaningful, sustainable long term goals either, so I recommend getting help in the form of talking about it. People overestimate their ability to call themselves on their own bullshit, but the ability of someone else seeing our self-deceptive patterns outshines it. Find a loving, caring professional invested in your growth and slowly make adaptive changes to this whole system. Slowly build such a nourishing, satisfying life that the shallow stimulus of internet feels like a waste of your life.
