I just started Zoloft maybe close to 4 weeks ago. The first week the pharmacy messed up gave me 25mg 3x a day. After five days on it, i stopped taking it and called my Dr to tell them I won't be taking it. I vomited , my head felt like it was in under water pressure, i screamed at the pain and I'm not one to wince at a stubbed toe either. My heart was racing too, it was frightening. So I linked up with my Dr and she said that's too much, that the 25mg was to ease into taking higher doses down the road and asked if I wanted to switch or stay on it but in the intended method. Just once a day.
I didn't mind still being on it since I didn't want to have to wait again for the meds to be sent to my pharmacy.
She instructed 4 days off of it, 3 days half pill and then one pill a day.
So technicallyy I have been on it for 2 and a half weeks with varying doses at first.

My side effects have been the "manageable" dizziness, lack of appetite and nausea.

I wonder though, I have been feeling a lack of motivation to do regular things other than playing video games which I never really touch. I mean I have had my PS4 for exactly one year and I have not finished the first game I've gotten and also barely opened the second game that came as a gift the same time last year. The only games I devoted time to are arcade games for better part of an hour.

I have been having trouble getting back into things that are of interest to me like audiobooks. I can multitask chores and listening to audiobooks all day everyday. I'm slowly getting back into them with dedicated time before bed. There have been times where I asked my partner to stop talking to me about her day because I can't focus on what she's saying and it starts swirling in my head.

Some of the days this week I forced myself to do chores even though I never needed to put a lot of effort into keeping my area clean, at least not since I moved in with my partner. What really buggs me is that almost immediately after or after some time has passed I kind of check out. Like my mood has shifted or just gave up with a punch to the brain. It's kind of like a drunk feeling, like incapability. I described it today as I was thinking about it as losing time. Not in the sense as blacking out because I am aware of what's going on but the mood affects me, I like cleaning and doing things. Basically I'm just sitting on my ass guiltily.

So I was wondering if one of the side effects consists of some like this and I haven't run into it yet. Maybe it's just the dizziness part of a SE but it's been really frustrating. 

I forgot to mention that I was basically bedridden for my first five day attempt and I'm just thankful it hasn't been like any of that hellish nightmare. Idk if it has some part to play with what I'm feeling now.

I would like to know some opinions from you guys because honestly I haven't been able to make a decision on my own since all this started, my head gets clouded when I start thinking too deeply about something. (Ex: making plans or cooking )

I know it takes time for it to stabilize, 4-6 weeks.

TLDR: I started Zoloft 3 weeks ago and haven't been able to have a proper thought or make a proper decision, i assume it's because of dizziness or something. I want to do more chores but all I seek out is playing my game and I feel like I lose time at the end of each day. This isn't my usual behavior, I haven't touched my PS4 in months, I don't think it's bad for me though. What concerns me is that i after I do chores I sort of check out, my mood has shifted and I want to do nothing for no reason. I have the energy but no more motivation. I am not usually like this, I have been working on home projects that have stopped as well as no motivation to clean even though I don't mind it usually. I would ask for perspectives on this and tricks or if it'll pass or something on the matter. I don't like when a week has passed and I was barely there.
