Feeling sick while bulking

This is my first time doing a proper bulk, and I have been feeling very uneasy and off balance everyday especially after a workout. Is this normal? Or could I be leaving something out in my diet that is essential? I’ve mainly been eating lean meat, low glycemic carbs and fruit

Edit: I’m 5’11 170lbs I’ve been eating around 3500 calories a day
