What Will Be The Outcome After Leaving Trazodone?

Greetings all. I m curious what the outcome would be if I quit Trazodone. I went on it after brain surgery in 2002. My 2nd under the knife, 2 other times prior underwent radiation procedure. Also between 2000-2002 times were dramatic, Mom long time suffered from same thing(nf2), died a month prior to the 2002 surgery. After awaking from that surgery and becoming paralysed entirely on left side of face, I was in a panic state of mind. That panic started a year prior after my second gamma knife surgery. Didn t realize back then, but thinking back, there was a few times where to panic came out through speech. Moving on..I was put on 25mg of trazodone, didn t do much, or last long. Then 50mg. That did it, and I ve been on it every since. I started to feel the panic/anxiety in 2010 and have been dealing with it ever since. I had two minor facial procedures (eyelid surgery) in 2012, and that kind of tip me over the boiling point. I had 2 full blown panic attacks. There were caused by abdominal pain. Very very painful. I ve always thought it was ulcer, but i m not so sure, it s almost like the sink is clogged? all the gas, acid, everything just gets stuck and doesn t move. I had it a few times when i was 17. After a year+ trying to figure it out, I quit coffee after supper and that stopped it. It took about 8-12 months to get over the affects of those attacks. I d always find myself tense, my hands would always clench up, or grabbing my shirt without even knowing. Same goes with other muscles. Only thing that remains is when I do something like house work, moving furniture, mow lawn etc. , my lips will be very red. the panicky feeling is under control for the most part. But after those attacks it just feels not that far away. If i ever need surgery I m gonna definitely seek max trazodone or something. with all this said, is trazodone even working any more? does the body over time develop resistance against it. It didn t calm me down one bit when I had those minor surgeries, or every day since 2011. what im wondering is if i quit, will the panic increase and become unbearable or no change? if i do need more surgery in future I will seek help, but nowadays manageable. I wondering if the 50 mg is still helping out. Mike
