Amoxicillin
"I'm on Day 5 out of 7 and am calling it quits and try a different one tomorrow. The side effects hit me all at once on day 3. I got extreme exhaustion and muscle weakness. I couldn't even lift my arms without feeling exhausted. I got really irritable and extreme mood swings (yelling, crying). I got heart palipitations and extreme anxiety/paranoia. Strange rubber feeling in mouth, weird thoughts. On day 4 I started hallucinating a bit (nothing extreme but it was terrifying). Every muscle in my body aches. Oh and I checked to see if my infection improved with an at home test and it's still there! I quit, this is honestly the worst drug I have ever had in my life and didn't do anything. I can't wait for this to wear off."
