Since my onset 12 years ago, it's the first time that a doctor proposed to make a CT of my head, which I did , and guess what the results are: I have had a stroke at some point in the past without realizing it, but it cannot be determined at which point exactly I've had it. It's fair to say I've abused with methamphetamines in the past. I've taken no more than 20 times, but they raise the blood pressure a lot so this is one possible explanation for the stroke. So the doc told me there's a chance this could be the reason for my fatigue. Or it may be not, it can't be determined for sure. So, I didn't realize I had a stroke and haven't had any treatment. It's both good and bad that it recovered by itself. It would have been better if I have had a treatment though, but ... whatever happened happened. If this is the reason for my chronic fatigue I would be glad because I don't have diagnosis for more than 10 years.
