Hi everyone, It's my first day on 40mg. I'm usually someone who struggles with fatigue and sudden exhaustion/sleepiness. Today, I took the pill at 5:30am and have felt fully awake and energized all day. This is unprecedented for me. Usually I find it hard to go a weekend day without napping (can't very well nap at work during the week, though I really wish I could most days!) There's only one problem... The anxiety is killing me. I've felt a crushing sense of anxiety all day. The kind with an ache I almost mistake for hunger. Can someone who perhaps has experienced anxiety as a side effect shed some light on whether or not it's a temporary side effect and it should wear off in a few days or if there's a chance it's here to stay? Should I talk to my doctor about it? Thanks!
