I tend to think of food supplements as innocent, and no stronger than, say, live yogurt. Wow, big mistake. I gave Fahed gingko biloba tablets for the last week. Poor man. I don't recall reading any warnings about what these tablets clash with, on the original bottle. Well I can tell you that they clash horribly with SSRI's (anti depressants). The poor man had an awful week but somehow managed to keep going. Once I realised what the problem was I stopped him taking them immediately. Last night he slept for 13 hours. Then he got up and took his car to the garage and when he came back he fell asleep again & is still asleep now. Poor chap. Anytime I decide to add any more food supplements to his daily routine I will read up on them properly. Currently feeling very guilty and negligent.
