Side Effects help!

Hi,
I am taking 25mg in the morning and 50mg at night. I was fine for about 2 weeks and now I am getting tachycardia, hands shaking/jerking, fogginess, and sometimes I feel that when i get out of bed I am a little dizzy. Are these supposed to go away? Because it seems to be working for my anxiety.

Thanks all

I take 200mg at night and have been on this dose for 4 months. The side effects do fade with time but I do still get shaky hands from time to time.
