Hi, I'm 28 yrs old in 25th week of pregnancy. This is my second pregnancy and I have a 4.5 yr old boy already. Sometimes, I have severe acidity which leads to sudden sweating, head ache, nausea leading to giddiness. Can I take Gelusil Chewable tablets in such conditions or any other food that would help me relax or any other medicine? Please suggest how safe is Gelusil.
