That's just ritalin. If you think it would be more effective to take a straight dose of 10mg than to use the time release mechanism, I think you could achieve this by getting the drug out of the pills you already have.
I am also using concerta because it is the only form of ritalin legal in my country. I don't really notice a difference compared to taking ritalin the other way.
Extended work from home finally pushed me to get diagnosed (ASS + ADHD).
I'm now on 2x 10mg methylphenidate (ritalin). It has definitely helped, but after a few weeks I now feel habituated (is that the right word?). Unless something is on fire or past deadline I'm back to getting no work done. I do notice positive effects when combined with (too much) caffeine, but ideally I want to quit soft drinks (and I don't like coffee).
I think I will ask my gp to switch to extended release. I hope he's willing to help me find something that works best for me.
As a sidenote, I do with people could be clearer when describing their medication. Just say the active ingredient, dosage, and frequency. Brand names can differ in different countries.
I'm on 6x10 mg of ritalin, and one thing that helped me with it losing its effectiveness is taking a reduced or no dose on weekends, and making a concerted effort to get plenty of sleep. I noticed that I'd be sleeping less when I took it, and eventually the ritalin was just counteracting how tired I was, but not providing any benefit beyond that.
If this is the effect it had you on then you're dependent. But luckily in my case, and I think most cases, it's not really a psychological dependency. It took me maybe three months or more to kick the physical withdrawal effects
Adderall is a mixture of several amphetamine salts including (25%?) dextroamphetamine and the formulas are subtly (and sometimes not so subtly) different between manufacturers. The key difference between Adderall and Dexedrine is the addition of those complementary amphetamines that balance out dextro's rough edges (Tracers!)
