terrible morning anxiety?

Im almost 4 weeks on zoloft and nearly 3 weeks on 100mg for severe ocd/anxiety. I never really used to have morning anxiety but now when i wake up in the morning my whole body feels so weak abd heavy, shaky, headachey and anxious feeling in my body i can’t really explain it. It usually goes away after an hour, ive alao been struggling a lot with sleep since ive started. Will this go away?
