Last summer after almost 33 years with CFS, I felt a rebound in the amount of fatigue I was experiencing. I had a new medical group and a new Internist. The Internist (having little else to offer) suggested I see a Psychiatrist in Mental Health. I decided not to argue. I happened to get a referral to a great doctor (IMO) who, after running his diagnostic checks determined my fatigue was not caused my depression issues (which I knew) and that I was in surprisingly good mental health considering I felt knackered.
One thing he offered to let me try was Adderol or Ritalin to see if they might help. At his suggestion, I decided to try the Adderall, but asked for the lowest possible dose. He thought that was 10 mg time-released, but discovered (to his surprise) that there was a 5 mg option.
Before I took it I had many second thoughts. But I had "one of those days" just after I filled the prescription and I took the pill. Did it help? Sort of. But I felt drugged. Like I was using speed on top of being very fatigued. I didn't like the feeling, nor did I like the long term risks.
I tried it a couple more times afterward with the same results. I felt 5 mg strongly (I tend to be sensitive to meds) and to me, it felt like a very unnatural band-aid covering up a problem. It "worked" to a point, but it wasn't for me.
Sounds like it fixed something, but there were still other things out of balance like hormone levels.
