Thanks for all your experience and particularly this. It is good to know that there is something that immediately improve motivation and concentration if I need to work hard for couple days.
What did you mean wen you said "after using modafinil for a "longer time"" - the longer time was 3 days or week or couple weeks?
I am doing a gym too for couple years, some solid gains already but never ate anything than proteins. I am thinking that I try it with creatine too, for mind and also for body.
Yeah I stopped drinking coffee for those side effects, definitely going to try L-theanine and see if that helps.
Regarding modafinil and "longer time" I ment maybe two weeks where I used it maybe 4 times a week, maybe 5. It was a really busy part of my life and I had to get things done. It may be okey to use it that often, but I forgot how important sleep and rest really is. (So it may have worked better if I would let myself actually rest, but I started working on modafinil even if I just had slept 3-4 hours per nigth for two weeks). I worked from 07:00 in the moring some days to 23:00. Ofcours I liked what I did too, but it helped and made me less tierd.
I think most people would recommend maybe everyother day. I liked to have two days in a row, then one day off.
(I only used it for two months, so I don't have too much experience. There are a lot of forums (reddit) for example that may offer a lot more tips and experience then I) - I also tried to be a bit careful, so some may maybe say to use more then me, other will say less.
-Also take it early on the day, it can be difficult to go to sleep if you are on a higher dose.
(Repeating myself: As already said, you have to try out different doses. Start small and increase if you feel like needed. Some people feel it is not much to help, others do. Some people need a very small dose, other needs a bigger. Just remember it can be difficult to go to sleep if you are on a high dose).
Regarding creatine it is good. Some people say you should have a "loading" periode where you use 10 g, but _I_ belive that is not needed (I belive it is just a trick to sell more to make you spend it faster). I may be wrong, but it still works great for me just using 5 g per day.
-Remember to drink more water with both this and modafinil - specially used at the same day.
-Regarding protein and eating, there are many apps that can help you get to your goals, leaning, bulking, keeping same size. I use an app, but it is for food in my contry - I follow it more or less, so I just get a better picture of what I need, proteins and calories, etc. It will also show how many calories you will need to eat to reach your goals.
Really recommend L-thenaine as said too. If you are tierd and need some extra coffee, it can be good to have some L-theanine to stay focused and not overly jittery hehe.
There are many good reviews on youtube regarding thenaine too. Helped with anxity, depression, focus, etc.
Maybe I repeated a lot here, but hope it helps. (Remember, this is all me, person experience we are different and I have no medical education, so I don't really like to give too much advice)
