I suffer with anxiety which if prolonged leads to depression and have been on and off ADs for many years, having tried most of the popular choices.
My GP prescribed Mirtazapine after a period of acute anxiety about 3 years ago where I was effectively living in a continuous panic attack to the point I could barely function. Sleep was out of the question.
Everyone's experiences of Mirtazapine will be different, however mine were as follows.
Firstly, it was amazing for getting me to sleep. Ironically, the smaller the dose, the greater the sedative effect. I've tried 15, 30 and 45mg doses.
I'd take a pill at 10pm and barely be able to keep my eyes open 45mins later and would have a great night's sleep.
In the morning though, unless I (or someone else) forced me to get out of bed, I could fall back to sleep very easily. I remember one weekend literally lying in bed all day, half awake and having a second full night sleep without ever really waking up properly. You have to force yourself to get up.
before my body got used to it, the first few days were difficult in that my head was very foggy, my mental processing inhibited and all my creativity restricted. I remember at one point actually slurring my speech slightly such was the level of background sedation.
Whilst this was a real problem from a work perspective, it was a massive and hugely welcome relief from the panic attacks and anxiety, and to be fair, it was the Mirtazapine that broke the cycle for me.
Once I've levelled out on the drug, the sleep and getting up in the morning situation remained, however the day time alertness did improve, albeit not fully - I was always conscious that I was under the influence and never quite felt natural.
My panic attacks and anxiety had stopped me from eating and I;d lost about 2 stone in weight, so the carb cravings that came with the Mirtazapine where initially welcome and I put the weight back on, but then it became a challenge to not over do it. I am well disciplined so this was not a big challenge, but I can see how so many put weight on with it. There are times when you are desperate for bread, cake, cereal etc and no amount of food satisfies.
What I will say is that Mirtazapine did nothing for my depression, in fact it made me a lot more irritable and short tempered. I tried all three doses but they were all the same. Brilliant to relax and go to sleep, but no good for me as an AD.
I still have a few boxes left of the various doses and reach for them in an emergency if panic has gripped me, to ensure I get a good night sleep and don't lie awake in the night with my heart pounding out of my chest uncontrollably for hours and hours. I always regret it in the morning when I'm groggy all the next day.
The only other thing I will say about Mirtazapine is that they were the only anti depressant that didn't give me sexual dysfunction.
