My son has been on the shots for nearly 2 months. They have him on a 117 mg injection per month at the moment.
When he came home from the hospital, they also had him on an anti-depressant - 10 mg/day of Trintellix. He stopped taking it when he came home, but recently said he’d try it again, but it’s too soon to know if that was the difference.
I was so hopeful when he came home. He stayed for 10 or 11 days because they let him come home as soon as they gave him the first 2 starter shots, letting me know he wouldn’t be well, but should gradually improve. And, he did. He was much calmer & happier, not paranoid, and talked less & less about his delusions each day.
He also soon started talking about maybe he could learn to this or that to get a job, and maybe he’d move out on his own - all kinds of things. Now, the delusions seem to have came back, and he’s also showing the lack of motivation you talk about.
He does bathe daily right now, sometimes twice a day, and he’s taken to shaving his head religiously, so he looks very well groomed even if he does kind of live in sweats and slippers these days. No complaints - I’m just happy he’s clean.
He doesn’t do much to clean his room, but he’s not doing much to make a mess either. We pick up any dishes or clothes every few days and empty the ash trays, and it’s mostly OK. He does apologize for not being able to clean up as much as he thinks he should.
So, I think we’re in the same boat you are, except for I’m trying not to complain too much because he is still so much better than he was when he went into the hospital. But, I was so hoping that his earlier motivation would stick. People keep telling me to give it at least 6 months to make sure it’s effective, and he’s only 2 months in.
I have some of the sarcosine. Maybe I’ll try giving him that again. When I first got it, I had to put it away. He was getting what he felt was a mild high off of it, so he was taking a ton of it. I don’t know if you can OD on it or not, but he probably went through a week or two’s worth in a single day.
Sorry - no answers, just letting you know I’m right there with you and have no idea. My guesses right now are that he was way sicker for much longer than I knew, and it’ll take him longer than I thought at first to get better. And, the Invega injections seem to do absolutely nothing for his anxiety levels - especially the social anxiety. I keep hoping the Trintillex will help there if I can get him to take it consistently for long enough. At least he’ll take a pill now - before, he wouldn’t take anything at all orally.
