"Dopamine Detox" and "NoFap" guys are trying to get you frustrated so you're easier to radicalize. This is a long and storied fascist recruitment tactic. The worse you feel the more likely you are to find community within their circles, and that's when they get you.
Buy some supplements that contain Vitamin D and Iron. Most people are deficient and it affects their mood. I got some meal replacements that basically contain everything and it's kept me in good spirits while everything is going to shit. I should be depressed, but I'm not.
EDIT: Iodine too. The over-the-counter stuff is called "kelp" and the reason they don't put it in multivitamins is because it metabolizes into a substance that in excess will give you gout. Iodine is hard to get from your diet so having supplements every now and then is important.
Tyrosine. It's a dopamine precursor. By itself, it mildly increases focus just enough to get non-preferred tasks started. It also makes completing tasks much more rewarding, which can start a positive feedback loop that leaves your space much more livable/less depressing.
Supplements suck that way, sorry. I've found a couple brands that work for me (Nature's Way, Horbäach), but I'm no supplement expert. I'd try to find a mid-price option that didn't seem too sketchy.
As for nootropic stacks and whatnot: never heard of them, although they seem interesting. I personally take 2g of tyrosine along with vitamin D and a vitamin B complex (plus a couple medical rx). I would start at 500mg-1g, and add more after a week if you felt you needed to. I have taken tyrosine with omega 3s but never regularly; I didn't notice an interaction at the time.
