I use restavit 3-4 times a week to help me get to sleep. A quarter of a tab more often than not is enough to send me off to nodland without too much of a bodyload the next morning. I am wondering though, has anyone used this for an extended period of time? Are there any problems with this at all? I haven't been able to find any info on this. All I have come across is "don't use this medicine for more than a few days" without explaining why. And if it's only a quarter of a tab, that shouldn't be a big deal, right?
