That is good news about feeling more clear and 'with it' after taking your Vit D.
Can you take it with food next time to try and avoid the stomach upset?
Vitamin D is absorbed best when taken with food, especially a meal that includes fats...so doing this will not only help you to utilize the suppliment better, but hopefully also help prevent the stomach upset.
Hope you continue to feel better and better!
