absolutely no

havin coke sodas wil obese ur baby.. it shud b avoided..

The options you said are not worth trying especially this period. It's always better to avoid them. As Sheeba said, try to have biscuit or rusk as you wake up, drink lots of fluid, tender coconut water, lime water. This will reduce vomiting sensation and you will feel good

try fresh lemon water

woah... not good... you will already have enough gas to deal with than add mire with carbonated drinks.. try having dry carbs like rusk or biscuit as soon as you wake up,  before getting off bed.. cumin seed tea is another good remedy..
