I have been a regular exerciser for about 3 years now. I'm a 25 year old female weighing 121 lbs at 5'5" (just in case any of this will be pertinent). I typically like to run, bike, speed walk or use the elliptical for my cardio anywhere from 30-60 minutes 5 times a week. I then do about 30-45 minutes of strength training 2-3 days a week.
Now here's the problem: if I wake up and do this first thing in the morning, before eating, I'm perfectly fine. However, if I do this in the afternoon or early evening I will ALWAYS, ALWAYS, ALWAYS get very, very nauseous. The only way to fix this is to curl into a little ball until it is gone, which can take anywhere from 30 minutes to an hour. It is SO annoying and also a little worrisome.
I've tried many things to fix this, eating before, eating after, drinking water, not drinking water, eating something salty, something sweet, so on and so forth and nothing works. I know the solution is exercise in the morning but that's not always possible. I would just love some ideas on what it could be or would like to know if anyone else suffers from this.
A few other things, I eat very healthy (am a vegetarian, moral reasons, not health), drink lots of water and rarely eat poorly, so I don't think it's diet induced especially since it never happens in the morning, whether it's before my breakfast or after, I'm always fine.
So after my life story, can anyone help at all?
