There are some people who pollute our mesoirah by claiming that we should not drink on simchas torah.
Rabboisai this is utter apikorsus!!
Chazal switched duchening to shacharis for a reason! It is ossur to be meharher after them and if they made accommodations for drinking, it is the height of chutzpa not to. V’chol hamarbeh harei zeh meshubach.
