Two weeks ago I was very tired all the time but it seemed, at times not as deep and the thinking issues were intermittent during the day but I certainly had focus issues in the evening. The phantom smells(s) - mostly of smoke were still intermittent but I noticed they happened at night, usually after dinner.
Last week I started to feel normal in the sense of not having the fuzzy brained with lack of concentration issue every day. The sudden wave of tiredness come over me, also during the day, every day and certainly at night was lessening.
This week, it now being Friday, and I can say I feel "normal" as the majority of the symptoms are gone! I have been doing some coding and my concentration is amazing to the point that I worked until 8pm one night and had no issues the next day.
I shall still take it easy for the next few weeks to ensure that it's really really over.
