Thanks for writing in.
If he is having vomiting, chest pain
and sweating, you must take him to the ER and get him screened for a possible heart attack
. An ECG and echocardiography
are important. Taking ibuprofen on empty stomach can cause further pains too and lead to gastritis
. This should be told to your doctor. Stopping smoking may require professional help. It can be sorted out at a later date. Insist on him taking regular medications and following up with his doctor.
Hope this helps
