Hi I am on 40 mg and take my tablets in the morning. This has been for years. Yesterday I took it at night and am planning to do the same tonight. but its half way throught he day and i feel dizzy and not with it. Should i just take one now and start in the morning again tommorro w or shall I persist take one tonight and start to feel better. Does it sound normal whats happening or could i be ill with something else.
