Hello there, I have to say that I have used both of these medications so I would try to help you. I do know that it might sound strange but they are similar but in the same time they are different too. both of them are aids in making you more concentrated as well as more focused. However, I have also found out that the Ritalin (at least in my experience) is getting me a little bit too wired to focus properly for writing. I can say that it is pretty similar as if I have had a pot of coffee and after that my heart started to beating too fast. That’s how I feel on it. as I said, personally for me, the cardio effects are being more profound when taking Ritalin than Modafinil. I would say that those people who are trying to get “high” off either one of them then I am sure that they would surely prefer Ritalin rather than Modafinil (although I surely would not recommend you to do anything like that).
Well, on the other hand we have Modafinil that I personally have found to be a better drug in terms of study aid and if this is the purpose that you’re trying to get them then I would tell you to go after Modafinil. I one have taken it only 3 or maybe 4 times, however not so long ago I have ordered some more of it from edandmore (and now I am hoping and praying to the customs gods that it is going to arrive the soon as possible). When I have taken it, Modafinil had me alert for approximately a full day (24 hours) straight at a full dosage and even when I have taken Ambien it has not been potent enough to get me back to sleep. However, the good thing is that with the help of this drug I did have managed to get an “A” at my test for my anthropology without any prior research on it, only by using the modafinil as a writing aid and doing it all the last hours. I barely have had to get up and this has been only to go to the bathroom, in the time when I am usually not even able to sit still for more than few hours straight. I seriously can’t sit still for very long. I would say that this drug Modafinil did not had those annoying cardio effects that Ritalin had and it also has not been as “harsh” as the Ritalin has been for me. It is obvious from what I have said that Modafinil would definitely be my choice for a study aid compared to Ritalin so that’s what I recommend you to search for either. besides, it is having the advantage of only being a schedule IV drug compared to the Ritalin which is a schedule II drug. I guess that this is directly related to what I have said in the beginning of my post, the fact that for recreational use Ritalin would be better, if you’re looking to get high off it then Ritalin is surely better, that is why it is having a much bigger abuse or dependence potential whereas Modafinil has very little potential for those, and plus, I think that it is near to impossible to get high off from Modafinil so I guess this explains pretty much everything. Modafinil only makes you very alert and very focused, especially if used for schooling, without cardio effects or making you high.
But then again, I don’t want this to be taken as a professional medical advice, this is only my opinion and I would recommend you to go and talk to your doctor first and let him decide which is better for you. plus, all people are different and maybe somebody else would have different effects. good luck and I hope that if you would use anything it would be for the better.
