been on this for a week ,dont feel any differnce except pounding headaches and I mean really pounding

had to come off clomoprazine because of chest pains,typyical this drug worked in making me feel better but had to replace it.what does sulpiride supposed to do ? all its giving me is the pains in the head so far.psych doc gave me the oral solution,tastes revolting but wouldnt give me pills for risk of me overdosing.I take 200mg along side 60mg of duloxetine.Im having to take codeine pain killers for the pain.its supposed to be sadating but I have not slept for the past week.
