Shrimps, from my exp once you have eaten enough of beef reserve you stop eating it all that much. Buckwheat. Strawberries work better than other fruits imho. Try walnuts.
Exercise, but it only works best when well fed. It would be easier to analyze if you posted your diet and climate.
Fixing sleep doesnt work that simple imho, as you are supposed to fall sleep when exhausted, so regardless of when you are falling asleep you are better off doing your best until you do. Tried fixing by just going to sleep earlier but ended up just spending hours laying around. I guess the brain has no problem to stay active for more hours than there are in a day. With that said if already screwed probably best to just go full breaking bad and roll it to the next one, i found. Just go with the flow. Alarm probably works.
