Kathy, for me w/the caffeine, it isn't something new. I've mentioned about this a couple of times on here, but figure this might be a good time to explain what I deal with. I have a condition called Meniere's Disease, or MD. I first started having problems w/it about 25 years ago. But at first, I didn't realize that I had a problem. I'm also hypoglycemic, and thought I was just having problems w/that. So, I'd just eat a chocolate bar. After all, that's what the doctor told me to do. (I found out later that this was the wrong advice) But, I noticed pretty quickly that it didn't do anything for me. So, I went to the doctor. He told me I had an inner ear infection and prescribed medicine. This happened a few times over the winter.
Then, summer rolled around and it got hot! I live near the back side of the lake. One day, my son, the little girl next door and I took an inflatable boat, towels, toys, etc and rowed across the lake to the bathing beach to go swimming. Well, I got so dizzy I couldn't stand. And, there was not a person there I knew. (This was B4 the days of cell phones.) There was no way I could get the boat back across the lake. So, I told the kids to stay there and NOT go near the water. They obeyed. I took an air mattress, floated across the lake and staggered to my house. I got my car, and went and got the kids. I had to leave the boat there. My parents came over and watched the kids for me. I could not even get up off the couch to go to the bathroom w/out throwing up first. I called the doctor and he finally admitted it wasn't an ear infection. He told me I could go to a specialist, but he didn't think it was worth it cuz they probably wouldn't be able to figure out what was wrong. I went anyway. (And, never went back to that doctor.)
They ran all kinds of test-including one to try and make me dizzy. It worked. The diagnoses was Meniere's. Normally, it affects senior citizens-I was in my mid 20s. Normally, it's in 1 ear. I have it in both. And, there's not much they can do for it. But, there are triggers that can bring on an attack, caffeine being one of them.
In one way, I'm one of the lucky ones. I've been able to control it w/diet. I still have most of my hearing. The only really bad attack I've had in all that time was on my daughter's 20th birthday.
I'll still get attacks, but not that bad. Most days, I'm able to get up and do everything I want or need to do. And, I did learn that things that I love to do have probably helped me. They now do balance training for people w/MD. I ride horses and a motorcycle and did karate for years, all of which involves balance.
As long as I watch what I eat and stay away from smells that trigger it (cigarette smoke, diesel fumes, most perfumes, mums, etc), I do OK. But, there's always the knowledge that any day I could wake up w/no hearing, or so dizzy I can't get out of bed. When I get my dog, she will be trained from the get go as a service dog. I've been coming up w/a list of things that I'll need her to do to help me if I'm stuck in bed.
