Going from Lexapro to Zoloft (sertraline)

I have been on Lexapro since Mai 2015 ( about 7 months).It is the longest period of time that i have been on the same anti-D.I tried Citalopram,Wellbutrin,Cipralex,Pristiq,Paxil,Cymbalta,Lexapro and now Zoloft.To help me with these meds i also tried,Seroquel,Trazadone,Remeron.I gave all these meds a good long period of time before trying something else. Today is day 2 of taking half ( 10 mg ) of Lexapro and half (12.5 mg) of Zoloft.After 7 days i will then start taking 25 mg of Zoloft and see where it takes me.I started taking Anti-D meds in June 2013 so i could say that i have not been lucky enough to find the right one. I can also say that i am lucky because for the most part, i do not suffer much during the weaning period ( on or off a med).Like a lot of people who suffer from depression I also have problems with sleeping.As stated above i have tried Seroquel , Trazadone (twice ) and Remeron to help me sleep.I now have Clonazepam .50 mg to help me relax and sleep but i want to wait and see what will happen with the Zoloft before adding the Clonazepam .The Doc left that choice up to me but i will take the Clonazepam if the Zoloft hinders my sleep(which it does to some people).I just want to encourage the people who read this forum and get discouraged after trying one or two meds.I have gone through a lot of weeks (6 to 8 weeks per med) going from one to another and i still think that there is one out there that has my name on it.I really home that Zoloft is it even if it is in the same family of others that i have tried.

Thank you Karen.I am on day 3 and so far i see that the problem right off the bat ,is going to be insomnia.I already have this problem and Zoloft is just making it worse.Tonight i will try .50mg of Clonazepam to see if it helps.If the Zoloft works for the depression, I hope that in time, the side effect(lack of sleep) will wear off because i do not want to take a Benzo for a long time.
