Hi Just Wondering If You Can Help Me. I Have

Hi just wondering if you can help me. I have come to bed and I'm tired I'm usually asleep by now, but when I close my eyes and trying to send myself off to sleep I'm getting a tinge tingling sensation all down my body, my heart beat is loud in my ears and sometimes skips a beat, I have dry mouth and find it hard to swallow. But when I open my eyes I don't feel so bad.

I ate some fish earlier from the fish and chip shop, and I have had the hair dresser doing my hair shortly after that for a few hours, do you think I could have the start of food poising or could I have swallowed some bleach?
