I started taking Sertraline back in May of this year. First dose was 50mg then increased to 100mg, when I was still feeling really anxious. I take it mainly for anxiety. I increased it to 100mg in July and for a while felt ok (well as ok as you can feel on anti-depressants). But, the last few months I have been feeling really nauseous. I thought maybe it was viral, went to the doc and he said it was probably the medication. When I accidentally forgot to take one the other night. There was no nausea the next day. Has anyone else experienced this. A bit scared about decreasing the dose!
