More glutinous tonic regularly swallowed by dynamic person (6)

I believe the answer is:

gooier

'more glutinous' is the definition.
(gooey means glutinous or sticky)

'tonic regularly swallowed by dynamic person' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'swallowed by' means one lot of letters goes inside another.
'dynamic person' becomes 'goer' (goer can mean an energetic person).
The alternating letters of 'tonic' are 'oi'.
'oi' placed within 'goer' is 'GOOIER'.

I've seen this clue in The Times.
