Hey MiaGrace...
Hmmm...? That is a rather interesting question concerning "Ritalin"...
Cannot say that I have ever heard of 'Ritalin' being utilised by any MPN patients, thus far anyways...
However, in my understanding, 'Ritalin' is a known type of "methamphetamine" ... Hence, firstly, I personally would be concerned over its 'Addictive' powers.
In my experience, (for the control of severe bone & joint pains). I do use "Endone" which is not a "methamphetamine", however, it too is quite an addictive drug, & therefore I do try to limit my use of its benefits, in order to maximise its effectiveness... One of the unwanted 'side-effects' from the use of such powerful drugs, can be very annoying withdrawal pains... & again, in my experience... those withdrawals are almost as bad as having to deal w/ the pain that I was hoping to manage & overcome in the first instance etc...

)
Other well-known Methamphetamines, like Speed & Cocaine, are also stimulants that are known for being highly addictive, & in my own view, I would not be using them myself...
Fatigue!!!
I know is a very close & unwanted friend in my life too... There are other steroid types or classes of drugs, that can be most useful in aiding w/ fatigue., (
Prednisolone). Also, I do seem to vaguely recall, that 'Ritalin' was/is sometimes used to help control patients suffering from various types of mental aberrations etc.
Ritalin works by acting on the central nervous system (CNS). A stimulant that works by increasing the availability of the neurotransmitters norepinephrine and dopamine in your CNS etc...
Anyways, perhaps there are others MATES members that know more about 'Ritalin' use for patients of an MPN might come along shortly... Might also be worth asking the same question on MPN Voice too... As they have so many more members than we do etc... Just a thought...
My best way of managing my own fatigue levels, is by my anti-inflammatory style diet, exercise, and that ...
very special & wonderful magic of my "Raw-Beetroot" formulae ...
It really does work... Happy to explain more about creating & drinking Raw–Beetroot nectar, if you would like me to, just let me know ok?
I shall be really interested to learn what else you ultimately find out concerning the use of Ritalin for MPN patients too... So please do keep us all in the loop please...
Best wishes...
Steve
