This is a good product but the peppermint flavor is too overpowering
The sublingual Melatonin is ideal for traveling because it works almost instantly, so you can get to sleep faster than usual. I normally buy the orange flavored version and ended up with this peppermint one by accident (not paying attention), I found the taste much too strong and it seemed to create a burning sensation where I placed it under my tongue. I will stick to the orange version in the future.

I particularly love the sub-lingual
I've been using melatoning for yeeeears. I particularly love the sub-lingual. I use the 5 mgs and take two every night just as I go to bed and within minutes I'm asleep. I wake up rested and refreshed. Note: You have to be very patient with the dosage. Start with one..then add 1/2 a pill or another one. It works! The key is getting the exact dosage for you because we are not all the same. For example: I always take two. Very rarely I need one more, how do I know? Well, if I can't get to sleep within a reasonable amount of time I will take a third. Now, if I do this a couple of days in a row I start to wake up a little tired in the morning. Now I know I have too much melatonin in me so I may not take it the following night at all until my own body tells me it needs it.

No after affects
I've been taking Melatonin for about 48 yrs. And has no after affects. I take it as needed. I've taken 1mg to 5mg. depending what kind of a day I've had. The pill is very small. I like the orange and peppermint flavors. The best time to take it is about 45mins. before you would go to bed.
