Downsides of Trazodone?

I have anxiety and depression from C-PTSD. I have tried Sertraline and Citalopram and felt awful on both.

One thing I really don't want is sexual dysfunction and/or weight gain. Sertraline gave me a massive sweet tooth and Citalopram made me impotent.

Add to this, I am self-employed and can't afford time off adjusting to meds.

I was looking at Mertrazapine but that looks like it makes you drowsy and hungry.

SNRIs look like they are bad for withdrawal. I had terrible withdrawal from Sertraline.

I have just read about Trazodone. It seems too good to be true as it checks all the boxes: no sexual dysfunction, not as sweating as Mirt, works quickly and is fairly easy to come off of.

Are there any downsides? Does the sedative effect ease up after a few weeks?

Am I likely to be able to get this on the NHS?

Thanks.
