Feeling sick after an intense workout?

Question

I had not been working out much at all until recently when I began seeing a personal trainer.  Before this most of the exercise I would get would be playing low impact games like softball and I had not been going to the gym in at least 9 months.  I had got quite out of shape and this is when I decided to join a gym close to my job and got a personal trainer.  
I have been to the trainer four times and she works be pretty hard.  The workout is usually a combination of cardio and weights and she will focus on one muscle group until the muscle is completely exhausted.  Near the end of the workout I start to have a headache and then at the very end I feel nauseous (the first time I actually vomited after the work out).  The other three times  would leave the gym directly after the work out and feel nauseous the whole fifteen minute ride home but would usually start to feel better about 10 minutes into the drive and would be totally fine after about 30 total minutes since the completion of the workout.  
I asked my trainer if she thought this was a problem and she told me that I likely just had not done anything this intense in quite some time and this was the cause of these symptoms.  She also suggested drinking more water and eating a cliff bar and taking and emergen-c before coming in but I tried this yesterday and this did not work.  
It also seems that the cold air (it has been between zero and 10 degree F all week) helps so this leads me to think that I am experiencing minor heat stroke.  I am 5-11 28 years old and 195 pounds, do these symptoms seem reasonable and will they likely eventually subside if I power through it?  Anyone have any advice or has experienced similar situations?

Sometimes working your legs or doing cardio you're not used to can make you sick.,,But I think you need more substantial meals.  I workout 3 x week and yesterday I got sick (like you said) & dizzy.  I had just grabbed a handful of berries and an orange & did not drink my 2 glasses of water cause I was in a hurry.  I have not been sick before but the change in breakfast did me in.

Get 2 glasses of water in the morning and get protein.  A couple eggs on an english muffin is great.  Or some cottage cheese with some fruit.  Get at least 300- 400 calories in for breakfast, wait an hour, keep drinking water & workout then.

Your heat-stroke theory is plausible....that said, dress appropriately.  If you're inside drink water often during the workout, don't wait till you're done.  Wear a tank & shorts so your body can breathe and certainly don't wear a hat.

Outside dress in layers and remove them and you heat up..especially your hat.

Ok I'm in school for this kind of stuff so hopefully I can help... I recently just rejoined a track and field team, I'm not long distance runner though. So when we do training where I have to run (even short sprints) for long periods of time, around the end when I'm completely exhausted I sometimes feel nauseous. Keep in mind, I am training VERY hard because we need to get into shape quickly since are first track meet is in December. So the way I see it, next time you should not do the entire 45 min workout. You should take it a little easier and work your way up to the entire 45 minute workout. Try jogging once in a while, its a great way to get in shape and I promise that after about 4-6 weeks you will have no problem doing this video anymore!

I think your trainer is right.  Whenever I try a real hard workout after having been away, I get nauseous too.  For me it was always when I tried an intense cardio workout or squats and I would often get sick.  Tell your trainer to take it a little more easy for a few weeks until you get back into the mode.

I would experience this whenever I pushed past a plateau.  I am just getting back into working out, and I am going to take precautions to manage or at least minimize these occurrences.  I have noticed staying hydrated during cardio is very effective. I try to pace myself (not be too aggressive) and I do a cool down.

There have been too many times I have been violently ill, dizzy, puking or a headache.  And recovery time was sometimes slow, but I have noticed the symptoms dissipated quickly if I had a BM.
