I'm sorry to hear you have MS, my uncle has it too and it sucks. However, you misunderstand my post. As a former biomedical researcher I do not argue against these drugs having genuine clinical applications, such as your case. The crucial point is in your post, your energy levels have returned to pre-morbid levels, you are not suddenly Einstein because of these drugs. The people posting here seem to have the idea that taking these drugs will enhance their performance, that is not true...they don't discriminate on what they make you focus on. What these guys need to realise is that you can't cheat your way out of being a bit lazy, unfocused and of average intelligence if that is your make-up. The fact you are in full-time employment AND doing a Phd suggests you do not fall into this category.
The ms patient has a deficit in their performance because of a medical condition. The average person probably doesn't. The underlying cause of their lack of energy/focus won't be addressed with those particular drugs. It depends on the problem, maybe they lack focus because they don't like what they do, drugs won't help with that, they will just be more focused and productive in the field of procrastination. Alternatively they maybe depressed, if that is due to their brain/body being unable to produce the right chemicals they need anti-depressants. If they are depressed because their lifestyle prevents their brain producing the right chemicals they don't need drugs they need to change their lifestyle.
