... then I woke up exactly 5 hours I had a feeling like a thump in my throat but I also use to get this because of my anxiety I have REALLY bad anxiety to EVERYTHING. well this morning I was ok but towards the middle of the day I noticed when I was up walking my heart rate would go up even told my doctor about it they said these are signs of the medicine and my body is just getting use to it so I also shake sometimes and feel very energetic just sometimes though for the energetic does anyone else have these problems if so do you still have them and when do they stop
