I Tried Melatonin For The First Time Yesterday I Literally

I tried melatonin for the first time yesterday I literally woke up like 10 times !!! And everytime I would fall back asleep in a minute ! This is extremely weird because I normally don't wake up at night or I wake up just once and have trouble falling back asleep. I feel like I have an extreme hangover pulsating headache and I have to fight the urge to not fall asleep again. I have suspected I have hormone problems for a long time but didn't do any tests yet, could this be related to hormonal imbalance? I'm 22 year old male. I have problems with my sleep wake cycle very badly so this seemed like a nice solution. But i'm afraid to try taking it again cause the side effects are killing me... my gut tells me to drop the pills, or maybe try 1/5 of a pill next time. I took them on a very empty stomach yesterday maybe that's related to side effects ? Also getting really bad tinnitus and a derealized feeling. I'm not exaggerating, I just tend to be sensitive to some meds, And I never get taken seriously about this. My nose is really itchy possible allergic reaction? I do have very high allergy levels in my blood. I'm living on disability for unexplained fatigue/chronic pain problems. I used to be top notch health before my problems started when I was 16. I haven't looked into hormonal problems yet because I didn't have the money to see a specialist in the past. I have hard breast tissue under my nipple that started in my teenage years. I can provide more information about my health problems but didn't want to make this too long.
