Hi Jomo,
I was on 15mg. I tried 30mg for a very short while, but it proved too stimulating causing restless legs and affecting my sleep. For me 15 was my therapeutic dose.
I tapered for approximately two weeks and had hardly any problems, the odd sleepless night which I expected, but that was all.
Yes, I agree you have to reach a point where you almost have no alternative but to take medication or go on feeling grim for days at a time and taking the risk the toll that would take on your physical and mental health. So it's always a risk either way. I sometimes think I just want to be like other people who don't have to take anything and just get on with it, but some of us need the medication to just reach that level playing field that every one else functions on.
Take care now and have a nice evening
p.s There used to be a very nice member here who went by the name of Ingenious. He's not around any longer, but his posts are still here if want to look them up. He was on Mirtazapine and I always found his posts very helpful and positive.
