sun

Has anybody got any ideas what could be happening here. Things are getting weirder with me. I noticed last summer for the first time that if I had more than one session in the sun of about 20 minutes which would usually be for lunch and / or dinner then I would feel extra tired and drugged later...

Hi everyone This is such an odd one I would be really grateful if anyone else could comment. Was fine with sunlight all my life even through early-mid stages of illness. Then suddenly started to react badly. Incidentally I am not light intolerant in the house - I like really bright bulbs...
