I don't know about a lot of the rest of your post, but this bit is key. If you aren't getting enough sleep, nothing will help. The legends of politicians and executives who sleep 3 hours a day are either outliers for whom 3 hours genuinely is enough, or speed-freaks, or often enough both.
Actual creative workers and engineers require a different set of brain functionality, which requires deeper concentration, and hence need more sleep.
Another tip that worked for me is not eating any fast sugars at all.
I agree to this but I think the bigger problem is - How much more is actually "more"? Do you any literature about how to actually find your sleep length time?
Among other things, the book talks about how much sleep people need. Almost everyone needs around 8 hours—it varies with age, but it pretty consistent among people at the same with very rare exceptions. For most people, being short even by just one hour (ie a night with seven hours of sleep) has a number of measurable negative effects.

What I know affects how much sleep I need or how long I should give myself to sleep varies. I'm female and follow a cycle closely linked to hormones as a baseline. If I wake up at night (for toilet, etc), I need a bit more time. If I increase physical activity, I have an adjustment period that requires more sleep.
I'll also note that time of sleep impacts me. I'm better off waking after 9am (naturally this is 11am or so). I cannot always get enough quality sleep waking at 6am and 7am leaves me slightly deprived. I tried keeping a schedule even on the weekends, but I felt horrible and found it better to sleep a bit more to catch up.
Here is one example paper https://www.ncbi.nlm.nih.gov/pubmed/28545315 and while it isn't a direct example of how to find your own ideal sleep patterns, it does highlight the relationship between sleep and body weight in the study population and it again mentions the 6-8 hour recommended minimum sleep period.

AFAIK the only way to be sure is to either go to a sleep lab, or get an accurate tracker like the Oura ring, which reportedly has a 80-90% accuracy compared to sleep lab data. With that data you can see the distribution of your various sleep phases, and the people in the lab or the app will tell you how much of each phase you'd ideally have.
But, why not just experiment a bit? Sleep 7/8/8.5h for a couple of days in a row, and keep track of how you feel and how much you procrastinate. E.g. for Mac, the Timing app is great at tracking how much time you spend in each app - one could use the amount of "productive" apps (text editor, IDE, graphical editor...) as a measure of productivity.

Why?
I suffer from caffeine addiction: a cup of coffee in the morning just to make myself feel normal. I got terrible mental melt-down once I stopped coffee for a few days.
Plus some people just need more sleep than the 8hr average and need to wake and work later than most in society. I for example, have just slept 11hrs and woken at 11am, but I will get more done than if I had woken at 7-8am.
AFAIK almost everybody procrastinates (more or less), but not so many people are suffering from depression.
I don’t think that shitty tasks themselves can cause depression; it’s all about the social context of the work you are doing. Is your boss bullying you, or telling you that you are not important to the organization, or does she try to punish your mistakes? Are you working just to support a study you are not really into, because you think you owe it to your parents? Is there another job you would like better, but you dare not change jobs because you are afraid you won’t earn enough to support yourself? That’s the way to get depressed about the tasks you are doing. Sort out the social context, and you might even realize afterwards that the tasks were not so mundane after all.
- Like you said, going for a walk (activates beneficial genes, helps circadian rhythm)
- Stop caffeine as soon and often as you can. Sometimes situations force me to use a pick-me-up, but I try and stop the day after.
- Go to bed early (10PM ideally)
- Vitamin D, Magnesium, etc. also check out near infrared therapy to improve mitochondrial function
- Moderate exercise (overtraining has a bad net effect on nearly everything, so stop if working out makes you feel worse; if you have a heart rate variability monitor, you can use that as a metric for overtraining)
- Small talk (works for me to „wake the brain up“)
But really, 90% of the time I just have to sleep more. The others are just hacks to keep me going if I can’t get enough sleep (sometimes not easy with 2 kids).
