It's not normal to throw up often period. Please see a doctor.  Edit: it's not good to throw up often, it fucks up your oral health for one. I understand bulking is difficult but if you are seriously struggling, you may want to ease up a bit. Smaller meals and chewing more through solids and giving your stomach to digest a moderate amount at a tine reduces the stress and energy directed to digestive organs. Your stomach can only handle so much to function at a healthy and sustainable rate, too much is too much.
