Suggestions for the sour stomach?

I've had now two shots at 5mg and I'm really happy with the way things are going so far. But the sour stomach for those first two days is kicking my butt. I'm struggling to eat anything. I'm finding that juices are oK. So I'm loading up on fresh veggies juices and high fiber yogurt drinks.

I weight lift twice a week normally lifting about 10K over the course of my whole workout and today I only got in about 1500 k in three exercises and had to call it quits due to fatigue and stomach pain.

Does this get better after a bit? What do you find that you can eat that helps with it?
