I find SSRIs to be more of an anxiolytic than an antidepressant, Have you ever used SSRIs? If so what was your experience with them? Did they cause discontinuation syndrome or negative side effects? Some people find them very tolerable but for some people they can be harmful. A safer & more natural option might be supplementing 50-100mg 3x daily 5-HTP to boost serotonin production to alleviate anxiety. You still have to consider seretonin syndrome & medication combinations with 5-HTP but it's not associated with any of the other risks of SSRIs. I don't really know how it works but activation of 5-HT1A receptors may be the ones that are responsible for serotonins anxyolitic effects and invegas occupancy of them should be minimal 0-5%.
Benzos aren't blocked by invega either. No gabagenic is. These aren't really good solutions for anxiety other than short term use even then they can cause a worse rebound anxiety on cessation, you could ask your doctor if they would be willing to perscribe you any though. Maybe you could try L-theanine, Ashwagandha, Valerian (particularly if it occurs at night) or other more natural options.
Low magnesium can cause anxiety and some people find magnesium helps even if you don't have low magnesium.
St johns wort is similar to SSRIs too. I find st johns wort tea to be quite relaxing. It won't help lower invega levels because hyperforin content is non-existent. It's more about the ritual & than the compounds in it. Chamomile would be a stronger anxiolytic but still only mild. Even plain old green tea contains L-theanine only 20-40mg a cup but it's more just finding the experience calming.
You can even trying just identifying and reframing anxious thoughts & developing coping skills. they call it CBT when a therapist does it, I call it gaslighting. It sounds silly but why would i see a therapist for that when i could just gaslight myself instead and not have to leave the house.
I've found that breathing excercises can actually be really helpful, particularly leaning how to use breathing to lower heart rate. again it sounds silly but it really has saved me a couple of times.
Overall it's really worth looking into lifestyle, behavioral & cognitive approaches rather than using medications or even supplements.
excercise is also apparantly good to reduce anxiety, now energy levels can be a big challenge on invega but you could try and see how you go. There's yoga or pilates or even aerobics which may be better suggestions than running or cycling, really its just up to what you want to do, what you would find helpful, worthwhile and maybe even enjoyable, you could start small and set yourself goals to work towards. Some people really get into it. Apparantly "runners high" is just the brain releasing Anandamide & 2-Arachidonoylglycerol which are endocannabinoids. Also even weeding the garden for 30 minutes counts as moderate excercise and is a lot less strenious than most exercise. Yoga increases GABA and would be very good for reducing anxiety without too much energy expenditure. Going for a 30 minute walk every day while it may not have the same benefits as moderate exercise can be really good for mental wellbeing.
So Invega shouldn't negatively impair any of these approaches towards treating anxiety other than excercise because of energy levels
"Serum levels will continue to decline in the mean time & you may have less side effects which may or may not be related to the lower serum levels, some symptoms may resolve before elimination & some may linger after elimination. Some symptoms might not be caused by the drugs, like risperconstas tinnitus. There will better days and worse days. steps toward recovery are possible even while it's still active. Try to be kind to yourself. You don't need to push yourself to be %100 recovered especially while it's still in your system. You just need to get through today. If you look at it like that it might become a little easier to deal with. What symptoms are you finding concering? Are there ways these to address or treat these before elimination? Are there times when they are better or worse?"
