No you need the vitamins mines made me feel the same way so I started taking mines at night before I go to sleep. But I would ask your doctor to change your vitamins and see if that help
I used to take mine in the morning after breakfast...now I take them at night after dinner/before bed...so I just sleep through the being sick part after taking them
You can take the flintstone vitamins!!
I would sudjest to keep taking them they made me sick too but I went anf got the gummy prenatal vitamins n they worked great for me once I ran out I took the normal pill but my body was used to the extra vitamins so I was fine
