So I just became vegetarian 3 weeks ago. I went cold turkey. My wife has been a vegetarian for years now so I decided to join her.

My first week in I felt amazing, so amazing that I started working out.

Before this I was eating a ton of junk food and meats and drinking a lot of caffeine.

I felt great I decided to get a supplement that would bring me energy all day and help me stop drinking coffee every other hour. So I bough Cobra Labs The Ripper.

This made me feel even better, I take one scoop of this stuff and I feel focused all day.

All was well for the first 2 weeks, but the third week of this lifestyle brought me massive headaches that pretty much make me useless.

I am thinking I am not getting enough food in me.

I eat maybe 800-1000 calories, a day and Im 230Lbs. I did not know I was eating so low, I feel full with every meal which consists of veggies and rice usually.

Here is what I eat
I usually eat
Breakfast: 2 eggs.
Snack: some type of nut mix.
Lunch: usually veggies and rice.
Snack: protein shake or hummus and crisps.
Dinner: More veggies and rice.

So yea I need some advice. Do you think I am getting these headaches of doom due to not eating enough or due to the supplement?

Holy cow! I don't mean to be dramatic, but wow! You need to be eating 2000 calories per day, MINIMUM. Probably even more than that, depending on your height, weight, and activity level. I'm 5'11" and 165 pounds, and even I need to eat about 2000 calories per day to maintain my weight and energy.

If you have trouble getting enough calories, eat more calorie-dense foods, like legumes or grains (about 200 calories per cooked cup) or nuts (700-1000 calories per cup).

You really did answer your own question!
Eliminating, or even cutting down on caffeine and junk foods can definitely cause headaches. You really do need more calories

Oh h'll! That Ripper is full of caffeine and guerana, and aminos. More caffiene than a cup of coffee, which is between 110 and 175mg. Rippers got 200mg and guerana

If you want the headaches gone in the short term, get onto a very fixed dosage and schedule for the caffeine.
If you want the headaches gone for good, get off the caffeine. Cold turkey can make you feel like shiitake for a week, incrementally tapering down will make you feel bad for a day or two after each step down in dosage. The serum halflife of caffeine is 3-7 hours so you should get the headache 12 to 30 hours after lowering the dose.
I'm tapering off caffeine right now. For me the step-wise approach seems more tolerable, it takes longer but this way I dont seem to get the constant drowsiness and irritability I had for a week when going cold turkey before.

And, yeah, you need more complex carb calories.
