Issue related to medication prescribed.

Hi my name is arindam dutta. From last year I was having swallowing problem. My throat was hurting while swallowing food. Then I consulted a gastroenterologist he suggested me to do an endoscopy and I did. But he told that the reports are normal and gave me some medication for 3 months and told to consult again after 3months. Then after three months I went back he told me that there is no problem with u, you are just taking too much tension and prescribed me to take Rabsig 20, Ganaton twice daily and Tryptomer and also to take 6 mectin plus injection once a week I felt a bit better. Then again after 3 months I went back and this time he prescribed me to continue Rabsig 20, Ganaton once daily, Tryptomer once, Mirtaz 7.5 during bedtime at time, and to take Mectin plus injections once every month for six months and consult again after six months but Tryptomer and Mirtaz makes me so sleepy and my mouth and throat goes dry. Thes two are anti depressent Meds. Is my doc giving correct meds.??
