I had a severe concussion over a year ago and have cognitive problems, possible seizures so please be very careful, I was actually rear ended twice one right after the other throwing my head forward both times and hit my head on the steering wheel, or so I was told, I have no memory of it.

Please be careful, ER Dr told me not to get another concussion (try not to!) as each one can make things even worse.

Yes, the heat/sun bothers me a lot, was out walking my dog yesterday and it wasn't that hot but that darn sun made me nearly pass out, headache and felt so weak.

Take care.
