Japanese past tense and combining sentences, help please.

I have a phrase that says:

The man was 40 years old, and was standing to the right of the exit.

I know how to use past tense, and how to bind clauses together with the -te form、 in this sentence the first clause gets it tense from the final verb in the second clause, right?
That gives me:

男 の 人 が 四 十 歳 で 口 の 右 に 立 ち ま し た 。

But then in this one, where the first clause is in the past tense and the second one in the present tense, how will I bind the sentence together and give the information of the first part occurring in the past but not the second?

Yamamoto drank a lot of alcohol and now he has a headache.

山 本 さ ん は お 酒 が た く さ ん 読 み ま し た 、 今 頭 が 痛 い で す 。 ?

Could I say 読 ん で い ま し た Instead? No I don't think so..

た す け っ て く だ さ い 。
