I am 17 weeks and for some reason the minute I begin to fall asleep I wake out of it with my whole body feeling restless . My arms feel like they don't know where to go my neck tenses up and I get short of breath. It almost feels like anxiety and I cannot stop moving and I can't find a comfortable spot . I feel like I'm holding my breath almost . I've had anxiety before but this is not triggered at all. It's the minute I fall asleep and it wakes me right out of it . Anybody else feeling this ? Any advice ?
