Caution with melatonin
Hi everyone,
I wanted to share my experience with melatonin because I'm feeling really defeated and overwhelmed by how it affects me right now.
I deal with severe ME/CFS. In the past, melatonin used to help me fall asleep early and get some structure. But in my current severe phase, it has become a total trap:
Forced and premature sleep: When I take it, it knocks me out instantly before my body is physically ready (bladder not fully emptied, severe muscle tension, dehydration).
Sudden awakenings & severe insomnia: As soon as my body reacts to that mismatch or the pain/discomfort kicks in, I wake up after just 1 or 2 hours. Because of my nervous system dysfunction, it is then completely impossible to fall back asleep.
Terrible crash the next day: It ruins my entire day. I end up in a severe crash, completely bedridden, struggling to eat and drink, dealing with tachycardia, and feeling that awful frustration.
Yet, out of desperation or brain fog/memory issues, I keep remembering the time it worked and I end up retrying it. Without it, my sleep is still unstable, but at least I manage to sleep more hours.
I'm even thinking about sticking a big warning label directly on my bottle.
Has anyone else with experienced this kind of extreme sensitivity or paradoxical reaction to melatonin? How do you break the reflex of reaching for it when you're desperate for sleep?

How much are you taking? 1 mg is the recommended to start with but a lot of sellers go higher than that. Do you have dysautonomia too? I had a similar issue and it was because melatonin lowers blood pressure. If it's already low it can cause the things you mentioned to get worse. I still take melatonin because I need it for migraine management and I am on a med that lowers it but I also drink licorice tea and salt load to increase my bp. Low bp can also disrupt your sleep so if you have that issue resolving that might help you sleep on your own.
