The medication you are prescribed and taking deanxit
is for depression
and happi IT is a anti gastritis
Now since the symptom you are despcribing is not related to the medication quiting. It can be something related with the stress
level which may be there associated with working for long time on computers.
I would suggest you to have a ergonomically friendly computer set which can reduce the stress level and also try to have frequent breaks during your working hours.
In the mean time consult your doctor who have precribed the anti depressant
medication to rule out if there is some sort of depression is coming again.
Thanks and take care.
