dose in evenings due to feeling very restless in my arms & legs & kept waking up at night. Took the 1/2 dose last night & that seemed to do the trick, however this morning I am feeling really weird, almost like I was going to have some sort of a panic attack. Just really strange feeling, almost went home from work but I feel better now other than the headaches but now I'm kinda scared to take it tomorrow. Anyone else experience that weirdness?
