Nauseous, dizzy, lightheaded and shaky..

Got to feeling nauseous this morning which is normal if I forget to eat breakfast for a little bit (I was waiting for my toes to dry ;)) but I got up to eat which usually fixes the nausea rather quickly and I got really light headed and shaky .. I ate two sleeves of crackers an half a bottle of water and then I had to go to the bathroom feeling sick and nauseous still ... the shaking was awful and I couldn't stand with out getting black spots in my vision... I forced myself to get up and head into the kitchen and I ate a spoon full or honey to see if that would help the nausea and possibly the tremor ( maybe low blood sugar? ) then I felt like I was gunna throw up again but still never did made some toast and ate that with more water and felt a bit better figured I'd get a shower and was feeling great then almost passed out and almost threw up in the shower and I am still feeling nauseous dizzy and shaky ...

These spells have been happening on and off .. does it sound familiar to anyone .. I don't know what it is...
