Lack of sleep because of Paroxetine (Paxil), any suggestions ?

Hello all,
I have been taking Paxil since 31-May-2017.Its been about 9 days and I take it in the night.
For the first 4-5 days, I was taking 12.5 mg and then the doctor increased it to 25 mg.
Ever since I have been taking it, I have not been getting any satisfactory sleep.
I have tried taking it with Etilaam, no luck.
Even with Mirtazapine 3.75 mg, no sleep, I keep waking up in the night.
Should I reduce the dosage ? Should I take clonazepam instead of Mirtzapine for better sleep ?
Please help.

15mg mirtazapine for sleep ,3 and a half mm is for a mouse:shades:

Could be start up effects.
