Sertraline - Increasing the dose?

After a bit of a break, I was restarted on Sertraline a few weeks ago. The plan had been for me to take 50mg each day for the first week, and then increase to 100mg. Once I started on the increased dose, I felt wiped out, which I had found to be a major inconvenience. After a fortnight of feeling like this, I had then decided to reduce the dose back down to 50mg.

Whilst I understand that Sertraline is an anti-anxiety medication and not a heavy-duty anti-depressant, I am now questioning if I should increase the dose back up to 100mg due to feeling emotionally distressed. I'm thinking that if I can get back to that place of feeling wiped out, it might result in making me more prone to sleeping for longer, thus enabling me to at least have some respite from my emotional distress.
