A few months ago I took Vitamin B Complex for my anxiety. It solved. But the problem I got is because of using it. I feel a little weak physically. Such as getting a little more sleep, Making it a little harder to adapt to the weather outside, and Feeling a little unusual when I suddenly get up from somewhere. But when my anxiety problem goes away and stops taking vitamins. Then there was no such problem. Now it depends on vitamin B and why you are taking it. Every medicine has some side effects. However, it depends on the use. You are taking vitamins because of the problem. It is better to leave it as soon as the problem is solved.
