Most importantly, EAT. Stimulants kill your appitite so it's easy to forget to get enough calories in at the right time. Pay attention to what time it is and eat when your body needs the food and don't wait until the end of the day when you finally feel hungry again. You might have to force yourself to choke it down, but EAT.
This is a really good point, and one that's so obvious that it doesn't come up often enough and sometimes gets forgotten about as a result. Even when there are no tolerance issues involved, it makes a huge difference in how well stims work for me. Partly it's just eating enough, period, but I've found that even more than that it's eating the right kind of stuff at the right time. If I get enough calories for the day, but most of them are coming late in the day when the med's wearing off and my appetite is better, it doesn't do much good early in the day. Same thing if I'm getting calories throughout the day but the stuff in the morning is just a bunch of junk for the sake of making sure I'm having something
, like if most of it is just sugar from soda and stuff like that. For the meds to work well for me and for me to be able to get any work done, I have to make a point of (ideally) eating real food spaced out throughout the day, including plenty of protein. If I don't do that, most of the time all they're good for is keeping me from falling back asleep in the morning, so I'm awake and alert but still with no attention span, which is not terribly helpful.
