Seasonal fatigue?

Has anyone noticed if their symptoms, fatigue in particular, fluctuate over seasons and/or get worse in winter?

My symptoms are the opposite of yours - they get worse in summer. Mind you I live in a very hot, humid sub-tropical climate with average highs of 30-33c during summer, but it basically just melts my brain and my neurological symptoms become worse.

I actually look forward to winter. Mind you, our winter is probably like your autumn or spring.

I have the same fatigue all the year
