Hi Everyone ..... I thought I'd post here see if anyone has any advice.

I'm very new to cycling - have joined Team in Training and been training for 14 weeks for my first Century on August 23rd.

I have a problem of getting severely sick to my stomach when I've been on my bike for around 4.5 or 5 hours - so for me around mile 55 or 60. It has happened on the last 4 rides and last Saturday it came along with a pounding headache and no energy (I only finished 78 of the 82 miles scheduled). I have worked so hard with my coach and other teammates on my food - I've tried everything, energy bars, protein bars, granola bars, boiled potatoes, PB&J, fig newtons, Twinkies, Poptarts (my team likes the sugary things), crackers, pretzels, GU ... I've tried combos and nothing seems to help. My coach is at a loss as he sees me eating all along the route and at the stops. I'm drinking all my water - 1.5 to 2 bottles an hour.

One thing I'm not sure might be related is that I do have PCOS (Polycystic Ovarian Syndrome) - which means that I am insulin resistant because it takes higher levels of insulin to keep my blood sugar at a normal level. So I know that for me to lose weight (a whole other subject) I'm supposed to focus on a low-carb diet. So I don't know if there is a link to all the high carbs - if it makes the amount of sugar in my blood make me feel that ill. I just don't know. (Do have a call into the doc.)

Just thought I'd post for advice, stories, any guidance?? SO appreciated!
