What was your dose @Jhdiaz ? I think mine was 50mg. Heightened Serotonin is known to suppress appetite while Dopamine acts as an appetite stimulant. My guesstimate is that your Serotonin was greatly elevated leading to lower Dopamine, which triggered hunger.
Check this out:
" In some cases, serotonin appears to inhibit dopamine production, which means that low levels of serotonin can lead to an overproduction of dopamine. This may lead to impulsive behavior, due to the role that dopamine plays in reward seeking behavior.
Serotonin inhibits impulsive behavior, while dopamine enhances impulsivity.
Dopamine and serotonin have opposite effects on appetite; whereas serotonin suppresses it, low levels of dopamine can stimulate hunger."
So it’s wise to supplement tyrosine when on 5-htp.
