Ritalin 2.5mg (very small dose by the way ) taken every 3 hours has completely changed my life. I went from "needs improvement" to "outstanding employee" at work, what a difference it has made--I highly recommend it, I was diagnosed with ADHD 3 years ago, and it still works as effective as when I started because I keep the dose low and use it when I need it, I never take it after 6pm. I have more focus, more energy, calm, don't get upset with people like I used to, get stuff done now instead of putting it off, not to mention it cured my long-standing depression, and I've been thru a ton of crap in my life. Sounds like a wonder drug? It is for me...just what I needed, and I've tried just about everything under the sun. Ritalin is great for motivational energy and focus. Fill out an ADHD questionaire, and talk to a good doctor. Keep your doctor/patient relationship good by going to see your doc every month from then on. I would have cruised thru school and college if I'd have been diagnosed earlier, but better late then never. This drug turned my life and brain around 360 degrees...I've tried dexedrine, antidepressants, just about every illegal drug you can think of, but this was the chemical that made me know what it was like to be normal, happy and "energized" and "with it" again. It also stopped my drug cravings for the illegal crap. I found the ritalin worked better for me than dexedrine, but than others find just the opposite, you have to get to know your brain and body, try them both, and you will know which one is right for you. Remember also that ritalin is short acting, and usually lasts about 90 minutes. Twin lab also makes a drink called "choline cocktail" in powder form that you add to juice, about 1 tablespoon is good in juice...works well but does little to nothing to block dopamine in the brain, ritalin blocks dopamine receptors about 70% in the brain, so it is quite effective, this way you have more dopamine available to use so it doesn't get "re-uptaked" as quickly as it would normally.
