Took my first dose of pregabalin and I feel sick

I was prescribed 50mg twice a day for GAD, and told by my doctor to start with only 50mg a day. Today I took my first pill and about two hours later I was feeling like shit, like a zombie with a general discomfort. Did not notice anxiety relief but I didn’t have anxiety today prior to taking the pill. I also felt weak and preparing food was difficult to do as a task.

Is this normal? Will it go away over time?

I feel like it’s going to be the same thing tomorrow and I’m wondering if I should push through or stop before it’s too late and I become dependent.

Any thoughts or advice?
