Every time I take it, I get a slight "LSD" feeling! (*I kinda of enjoy it
Of course, none of you philosophers have ever taken hallucinogens so this question probably is redundant: Do any of those that have ever taken an anti-inflammatory ever had this, or a similar side effect?

6. Are there any side effects?
Less serious side effects include stomach upset, loss of appetite, constipation, diarrhoea, hearing disturbances, headache, dizziness, tiredness, change in mood. Serious side effects include severe stomach pain or tenderness, fast or irregular heart beats, signs of anaemia, unusual weight gain, swelling of ankles or legs, bleeding or bruising more easily than normal, yellowing of skin or eyes, dark coloured or cloudy urine, difficulty urinating, eye problems, signs of frequent or worrying infections, vomiting blood, bleeding from the back passage, black sticky bowel motions, severe dizziness, seizures, tightness in chest, or signs of an allergic reaction such as swelling of the face, lips or tongue, wheezing, shortness of breath, sudden or severe itching.
I guess 'dizziness', is the closest in the list above. However, it's still not dizziness, more is like the "time-dilation" conscious feeling that one gets on a drug such as LSD or magic-mushrooms.
