I Take Lorazepam 1mg Everyday. I Was Using Ativan For

I take lorazepam 1mg everyday. I was using Ativan for years but it became too expensive. So I switched to lorazepam. There was a period of adjustment where I didnt feel quite right but finally everything worked. They were manufactured by watson. I just switched drug stores for a significant drop in cost. The pills are made from Sandoz. I feel the same as I did when I switched over from the Ativan. Is this possible again. Especially that both of these are generic?
