So I did take my first dose of 5-HTP yesterday along with Vitamin B complex which increases its bioavailability and I have very mixed feelings, on the one hand, it completely eliminated my anxiety. I mean gone completely gone and I had pretty severe anxiety so that was a blessing. I haven't been anxiety-free since 2016 and it did improve my mood a lot and bring me a lot of happiness, but on the other hand that mood improvement seemed more like I was high on hardcore drugs, it didn't really feel natural or organic, it even seemed like it was hard to distinguish reality at times. As far as my sleep goes it was hard to fall asleep, but then I did get some quality sleep with very vivid and realistic dreams. And I also experienced some side effects like nausea and pressure in my head, some people say it's a pretty common side effect until your body gets used to extra serotonin and that it goes away in a week or so. I will see. For now I will keep the dose at one tablet a day and if the side effects continue I will lower the dose to half the tablet.
I also will stop using Curcumin since it increases serotonin and dopamine. I also heard that some of the side effects I experience are common after being off Paroxetine so that could be the reason as well. We will see. So take that for what you will, it's just my personal experience so far.
So yes it seems like 5-HTP does have side effects, none of them seem as severe as Prozac though which increases the risk of suicide especially in young people under 25, seizures, mania, serotonin syndrome, etc.
Also if you had so many problems coming off of it you are better suited to talk to a medical professional about how to lower the dosage and how to replace your medication. I am just mentally ill loser on the Tinnitus Talk forum after all, just someone who has interest in research and science.
Also, I worded my response kind of wrong. 5-HTP isn't the only option for you. There are a lot of ways to increase serotonin, dopamine, and noradrenaline. Just some of those include St John's Wort (serotonin), Curcumin (serotonin and dopamine), L-tyrosine (dopamine and noradrenaline), SAMe (serotonin), L-theanine (serotonin and dopamine) etc. So you need to really pick the best suited option yourself and see what works for you. But if you think coming off Prozac can be deadly for you, you really need to ask yourself if experimenting with yourself is worth the risk.
These are just my general thoughts. Take care. If you have any questions don't hesitate to write to me.
