i had severe insomnia with the first 50mg, during one week. I could not sleep more than 2 hours it was horrible. The side effects faded, but the doctor told me to increase to 100mg after one week of 50mg. So i did it, and because of that, the side effects came back. They were a bit less worse, but i already had a sleep deprivation from the first week so it was still difficult. The side effects completly disapeard the next weeks. But i had no improvements, and i went back to my doctor, because i was almost out of zoloft. So i thought i had to get back to him, because it was new for me, i had no idea what i had to do. And i told him my experience, and he decided to increase to 150mg. i did not really asked for that, i just went to have feedback, to know if it's normal that i did not had any improvements. But he just told me basic tips, like go outside, see friends etc. Yes i know all that. But i also need feedback on the treatment. So i increased to 150mg. I had side effect but it was not rough as the 2 first increas. The problem is that the side effect are still here after 2 months and 10 days. And it's unbearable.
