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.
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.
For reference:
- Ritalin, Concerta = Methylphenidate
- Adderall = Amphetamine
- Dexedrine = Dextroamphetamine
- Vyvanse = Lisdexamfetamine
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!)
