If you’re wondering whether or not insomnia is a side effect of Molybdenum, it isn’t.
I doubt this will help much if at all, but you might try taking that last tablet earlier in the day; maybe one in the morning and one mid-day.
If it’s really insomnia you have, you can try treating it with an herb called Ashwagandha (450 mg each) as well as 5HTP (100 mg each). Take three capsules of each every day but start with one capsule and work up to three by adding one of each every three days. Keep in mind that sleep is ultra important in rebuilding the immune system.
