I had every one of the side effects you mentioned at one point or another. They would come and go through the weeks of the initial side effects. If it's only been 11 days, then that is still pretty early, and it could take a few weeks for the initial side effects to wear off and go away. For me, it took almost 3 weeks for the initial side effects to wear off, but everyone reacts differently to this medication, so it's hard to say how long it will take for you. I think the insomnia side effect was the worst one for me. I didn't realize that some pills like Zoloft give you an energy boost. So, I stopped taking my Zoloft at night and started taking it in the morning or afternoon. I also avoided caffeinated foods and drinks as much as I could, especially later in the day. Maybe you could talk to your doctor about taking a sedating medication at bedtime. I think a few of the other people here have done that to fight the insomnia, so you might want to search for those posts. For the loss of appetite, I just tried to eat what little I could when I could. I do remember being a little more hungry at night, so I would eat what I could. It wasn't much, sometimes it would just be some applesauce or some yogurt or something like that. For the dizziness, headaches, tingling etc, etc. They would just come and go, and I just tried to power on through them and let them fade over time. Eventually, the side effects went away and I felt really good, so much better than I thought I would feel. That's what kept me going through the initial side effects, hearing from people on this forum that they eventually felt better or felt like their old selves again. I can't think of anything else. I wish I could help more. I hope the side effects fade for you soon. I hope you feel better soon.
