I have severe ahnedonia from an invega injection that I recieved 4 months ago. The drug blocks dopamine and seratonin receptors so stimulants and caffeine don't work. I can't feel anything and nothing makes me happy. I've tried 7 different medications including Vyvanse, Adderall, Ritalin, Concert, Modafinil, and Zoloft and none of them work even at very high dosages. Invega has a half life of roughly 40 days so it takes about 8 months to get out of your system. I'm depressed every day, I can't get out of bed and I have to rely on my Mom for everything. On some days i am suicidal. I'm wondering if any one has had a similar experience or knows how to get this out of my system. Are there any medications or supplements that I can take that would help with this? Ive never been so desperate in my life. Please help me.
