I likely will always take it. I can't even remember when my last OB was. The brand I take is called Laurilcidin I never thought I would be able to say that. I never thought I would not have my life ruled by this virus. The only reason I come onto this forum is not because I think about this virus or it puts a damper on my life but because I have found something that works. I have freedom and a normal life again and I remember feeling hopeless and in pain constantly. If I ever think an OB is coming on then I do take a few capfuls in a day. I used to always have antivirals on hand (acyclovir) but I feel confident that for ME this works at least as well but I think it works better. It's not damaging and it's healthy. That said different things work for different people. This is worth a shot. Very reasonable price wise.
