I go to a choir on a Tuesday monring. Initially I was on quetiapine as well but with neither could I take the music in.
You might try doing things like Sudoku or other games - even playiing Scrabble with someone - even keeping on patients dot co dot uk keeps your mind active.
A few years ago I was going to a fairly advanced French class at the CityLit in London with 20- or 30-something City lawyers etc - combined with the fact that I hadn't spoken French for a long time I found the class very difficult. I was able to do the exercies at home but it was unable to think on my feet. I don't know if you are British and on one occasion we were asked by the tutor to think of a celebrity that we would like to meet. I couldn't think of anyone - I might have said George Clooney or David Beckham - but I could only think of Andrew Neil he TV political presenter. People laughed. He was considered so naff and I couldn't think of anyone else and say someone more cool. It was fairly painful as you can imagine.
More rcently this year I organised a French conversation class on a Sunday morning. Of course, speaking a language one has to be on one's feet. In fact, I organised the class and we met then at a local park cafe. I found that when I even took the mirt in the evening that I couldn't think of the right word - although at the time my French was rather rusty. Only when I didn't take the mirt the night before did this correct itself. I have just left the group after a stupid disagreement with an oaf, but I was able to hold forth using the vocabularly that I knew.
About 3 years ago I remember complaining to my GP about my memory. At that time I used to go to a weekly pub quiz. I used to pride myself for coming up with the answers to fairly obscure questions, yet the answers just would not come in the short time required.
I have a Maths degree and I would pride myself on my intellect and yet I suppose felt that I was losing my grip.
Now I am off mirt, quet, Lithium and Prozac things are great. But I wouldn't be in my current position without them, I believe.
But I do sometimes get very depressed but these are more reactive. But I was advised not to work agaiin (I was 55 at the time - I am now 60) as when one is working you might be upset by some action of another person - this might not be intentional on their part). At work you can't go home and get away rom the source of your "irritation" and even if you did the person or the work is there the next morning.
But, look, I was in hospital for 8 months 7 years ago and I was given ECT at the end of that time. I was therefore seriously illl even when I came out of hospital, so they had to try anything to get me better. Only now am I well to the extent that unless I told people they wouldn't know. In fact, I am only now going to things,like social events, where people don't know and, I don't think that I am a "Martian".
I don't want to go through all the things that I have been through because I will find it upsetting.
I have no idea what your diagnosis is, but I would say to you or anyone else here is you have to decide whether the effect of the drug is worse than the illness. When I was transferring from Lithium because it was killing me ie it was effecting my kidneys my psych gave me the data sheets of quetiapine and chloropromazine (I think) and asked me to decide which I wanted to go on, looking at the side effects. Fortunately I was in a state of mind that I could do this - my sister is a GP so that I talked to her as well.
