Thanks for posting your query.
There are definitely good drugs which cause much less drowsiness
as compared to Oxetol
but the time to choose them is not good for you.
All drugs of this group need a slow tapering and slow building, patient may not have ideal response due to individuality. During exams you should not try any change, if you land up in side effects or under effects you would be in hot soup.
Once your exams are over consult a physician for switch over. Meanwhile continue the dose with which you have carried so far.
