Lorcaserin
"Took first pill yesterday. Noticed almost immediately no appetite. Got a hummus wrap for lunch & couldn't even eat half of it; I can usually eat the whole thing. Dinner I ate the other half then took 2nd pill. Now as I write this almost 14 hours later after that 2nd pill I wish I had never taken it & won't take it again. Last night chills. My arm tingled all night long & thought it was signaling a heart attack. That thought caused me a lot of anxiety & I could not sleep well. Got up twice during the night to go to the bathroom & had to hold the wall all the way there as my legs and back were in severe muscle pain. This morning had a hard time dragging myself out of bed.  Most meds seem to react fully on me.  I cannot take Belviq."
