Medication Malfunction

Oops, it finally happened. I stuffed up on the happy pills. No biggie I'd guess as it was only one day. Took an old prescription to the chemist and one box was only half strength of the pills I take. Didn't notice until this morning when taking more. Yesterday I'd only taken half the amount! A very big drop. Then today as I took what I was supposed to I ended up quite off my face. Dizzy, hot, weak, etc. Went home from work, was honest about it all, said it was my fault. Of all the pills those are the ones that shouldn't be stuffed up. Oh well, I survived.
