Try the strain Euphoria. Might not be available in the U.S but if you can get it, I think you'll like it.
I came across it by complete chance, didn't think much of it at first but its became my most favourite smoke to date. It isn't that strong and will allow you to smoke during the day with no red eye or couch lock. However on the night time double the amount and you know for sure you are stoned, but it still isn't the sledge hammer hitter of high tch couch lock strains. On smoking normally though, it's just like that relaxing feeling you get from a nice hot bath, if you think about it, you realise your mildly stoned, but you wouldn't even know it unless you thought about it, because it just slides you into it nicely. I've had 0 bad experiance on it, no panics, para, heart rate increase, sweats, shivers.. none that stuff I've had from time to time with heavy thc hitters. It's also not a bad mix with alcohol, where the other higher thc strains just end your night as it's easy to over do it.
