Hi. Female 32 years old. My gynae put me on StaminoGro 2 pills every night. It’s my 3rd night tonight. I wake up feeling very sick, nausea, headaches and no sleep at night. Should I stop because it makes me feel really miserable?

Talk to your doctor. As a general rule you should stop a new supplement if it gives you symptoms like you describe. But talk to your doctor about it.
Vitamin. This brand of vitamins is not available in the US. Looking at the ingredients it is just a vitamin. You did not mention why your doctor recommended supplementation. If trying to conceive you could just take another brand of prenatal vitamins or Folic acid. If your doctor specifically wanted this brand ask for an alternative.
