Hello. I am a 17-18 years old student and from a very young age I have been suffering from ocassional, though excessive stress and all the extra problems it has induced to me over the time (such as fevers, stomache aches, diarhea, problems with sleep e.t.c) For many years I considered this situation natural, until I thought it started to worsen and started affecting my life a great deal. So this year, since I have some very important and stressful exams, I thought it was the best time perhaps to take some dietary supplements (that won't overdo it of course, since I constantly feel tired ). For this reason, I visited two pharmacies and also came in this website to ask for an opinion. I would also like to mention, that as a more inexpensive solution I was recommended to take some B-complex vitamins for the whole year. Is this something that could help me with my problem? They recommended me the ones from the brand "Power Health". But I wonder if there are any other brands you would recommend. Thanks a lot for your time.
