20mg is considered a suitable dosage for someone who doesn't have ADD
K, a few things to say: first, illmantos do u take ritalin? if so, by cutting this out your panic may be tolerable; also ritalin at any dosage, 20mg, 10mg whatever, is not suitable for people who are not adhd patients or who don't have narcolepsy. ritalin is alright for some people when prescribed responsibly, but I made this post with the intention to make something clear. POINT: if you do not already have adhd or narcolepsy ritalin is not the thing to take to study, it won't make you smarter, it causes an illusion of intelligence, if you are not a patient, caffeine is perfect. Maybe speak with a Dr. because this seems iffy to me; the use of ritalin by any person who it isn't prescribed to is illegitimate, and the use of ritalin by people without adhd is even more inappropriate. If you have been diagnosed, you shouldnt have any question about dosages, follow dr instructions, but since you are asking if 10mg is a good study dose, il say ok, but il also say that it doesn't last very long, a better thing to do might be to take two half doses, and take the second dose about 2-3 hours after the first but in this case you still won't be able to study too long. for instance my intention when i woke up this morning was and is to study my face off, i don't use ritalin; for me a study session demands anywhere from 7-8hours on the low end to 12-14 hours on the high end, I'm not sure how long you are aiming for, but ritalin IMO/E did not meet my needs for this purpose, ritalin is the kind of thing that is good if your work wont take too long like 4 hours andif your task isn't very important to you, ritalin works for mechanical things, I love taking it when i dont study, but yea i just looked at op again and i saw you asked if 5mg would work, it might be all you need, you could even try 2.5mg bid (twice), or a 2.5mg dose every 2 hours would be alright as well, good luck, and an idea might be to think less about the fact you took ritalin to study and more the fact that you intend to study, good luckkkkkk, i am procrastinating, ugggh yea man hope all is well, and the effects shouldnt be anything too out of the ordinary.
