Metazapine

This must be an AD which is not normally prescribed for SAD.

I have been prescibed it also to combat insomnia but it is early days yet - I will persevere

Hi I took this med for about a year felt alot calmer and slept alot better but I felt I became a much quieter and reserved person friends would tell me so, came off it and started taken another one fluoxetine and feel alot more with I have terrible withdrawls but overcome that and fell alot better.

I had a similar experience with Mirtazapine to yourself. It was(supposedly) prescribed for me to help me sleep, but after 18months & severe apathy caused by this particular medication; I stopped & have started taking 5HTP(BD), 50mg twice daily. Even after a couple of days on the serotonin(5HTP) I am starting to feel human again, including having a good, healthy sleep. With a spark of life back. I was on 15mg nightly but even if the dose was doubled there was no improvement.
Anti-depressants do not work for me, and each time the blasted Dr's put me on them I feel worse lol. From my professional( I am a retired RN) and personal experience, these chemical straight jackets are thrown at us due to the lack of time, very high financial cost of other useful interventions & lack of an open-mind from the medical profession.
These are my own views, do not use them as authoritative.
